Types Of Fertility Hormone Testing
Considerable hormone activity occurs during the menstrual cycle, so testing for hormones, such as those listed below, should be done at a specific time during the cycle.
Medications, including birth control pills, can interfere with hormone test results. Women and men should tell their physician beforehand about their medications, and may need to cease certain medications before fertility hormone testing.
How Do Testosterone And Estrogen Differ
Testosterone, the key hormone in men, is the chief regulator of muscle tone and lean body mass, or the very essence of what gives a man his masculine appearance. A normal level of testosterone is a broad term, making deficiencies difficult to detect. The hormone is produced by the adrenal glands and testicles, with levels highest in the mornings and decreasing throughout the day.
Testosterone also regulates a mans sex drive. Lack of sexual desire and performance, often associated with low levels of testosterone, or low T, is a common complaint from men as they age and hormone levels drop. Sex drive and performance, however, require the presence of both estrogen and testosterone.
Estrogen, by contrast, is the hormone responsible for sexual and reproductive development in women and is also referred to as the female sex hormone. Estrogen is really a group of hormones that includes estrone, estradiol and estriol. Estrogen is produced in the ovaries but also by fat cells and the adrenal gland.
Stimulation And Suppression Hormone Testing
We use tests called stimulation and suppression tests to evaluate a hormone imbalance. We give you hormones and other substances that either start or stop your production of certain hormones. We then evaluate how your body responds.
Common types of stimulation and suppression testing include:
- Growth hormone response to glucagon: We inject a hormone, glucagon, into muscle tissue and measure growth hormone levels over four hours. This test helps us confirm or rule out adult growth hormone deficiency.
- Cortisol response to cosyntropin: We give you cosyntropin, which acts like ACTH . ACTH is a hormone produced in the pituitary gland that stimulates the adrenal glands to produce cortisol. We measure cortisol levels every 30 minutes for one hour. This test helps us confirm adrenal insufficiency.
- Glucose tolerance test: We give you a sweet drink, which should lower levels of growth hormone. We measure levels of growth hormone in the blood every two hours. This test helps us confirm acromegaly.
- Cortisol response to dexamethasone: You take a pill at night that should block cortisol production. The next day we take a blood sample to measure cortisol levels. This test helps us confirm or rule out Cushing’s syndrome.
- Metyrapone suppression test: You take a pill at night that should block cortisol production. The next day we take a blood sample to measure cortisol and ACTH levels. This test helps us confirm or rule out adrenal insufficiency.

Hormone Testing: What To Check And Why
Questions about hormone testing are common among my patients and on social media. Women want to know which hormones they need to check and why. They also want to know what hormones and other biomarkers can be tested at home. In this video and accompanying article, I cover the biomarkers that I check for myself and my patients approximately once per quarter. Note that not all biomarkers I discuss below have been validated for blood spot testing versus the gold standard of a blood draw for serum testing, which is what I use for treatment decisions. Still, one can infer trends and screen for problems to investigate further. My highest recommendation is to perform serum testing for all treatment decisions, though that may be difficult during quarantine and lockdown. I created this video to show the blood spot test that I am performing in lockdown, even with the caveat that it is not considered the gold standard for all tests mentioned in this article.

What Types Of Issues Are Diagnosed From Hormone Tests
“Many conditions that mimic hormone imbalances are not able to be diagnosed by a simple blood test, therefore, it is best to see our doctor if you have concerns,” Dr. Kasper added.
Introduction To Laboratory Tests
Laboratory tests seek to answer questions raised by doctors after talking with and examining the patient. For example: How can I confirm the diagnosis? Are related illnesses present? Is the treatment working? Are side-effects present?
Laboratory tests are usually carried out on samples such as blood, dried blood spots on a card, saliva, single urine samples and 24-hour urine collections. The type of sample will depend on what is being measured, the accuracy required and/or the age of the patient. Once the sample is taken, the patient does not need to be present for the results to be produced.
The results of hormone tests when healthy vary in response to natural pressures such as food, drink, rest, exercise and the menstrual cycle, which can make results in health and disease overlap. In dynamic tests doses of hormones, drugs, glucose and natural pressures such as exercise or restriction of water intake, are used to control the influences on results and make them more predictable.

When And How To Test Hormone Levels For Women
A fertility hormone test involves just the removal of a blood sample to determine the levels of all the reproductive hormones described above.
It should be noted that the blood test should be done between the third and fifth day of the menstrual cycle, that is, within 3-5 days after the start of your menstruation, since your hormones are in basal levels and can be compared with the reference values.
The first day of the menstrual cycle is considered the first day when a woman has a heavy bleeding, marking the start of the menstrual period. The previous days, even if mild spotting occurs, are not considered the beginning of menstruation.
Nevertheless, the hormone progesterone should be checked on day 21 of the cycle to determine if ovulation has happened or not.
Finally, AMH testing can be done anytime during the cycle, since its value does not fluctuate through it.
How Hormone Testing Works
Hormones can be tested several different ways blood, urine, and saliva. Which one is best for you depends on your symptoms or any diagnosed conditions. In general, for fertility and to monitor the status of hormone replacement therapy, blood tests are sufficient. When evaluating hormone imbalances like PMS, PCOS, and chronic fatigue choosing urine or saliva will provide you additional insight into the root cause of the condition. Its important to test your estrogen metabolites and the circadian rhythm of your cortisol to obtain a complete picture of your hormones and evaluate any potential hormone imbalance.
If youre on birth control, your hormone levels on any test will be suppressed, because birth control pills contain synthetic estrogen and/or progesterone which deplete your bodys natural production of these hormones. Once going off the birth control pill, your body should naturally take over this process again, however that can take up to 12 months to regain a regular menstrual cycle.

There Is A Similar Test Advertised On The Internet Can This Test Be Taken At Home
Samples of urine, saliva, faeces and finger-prick blood, which can be collected at home, are currently used by the NHS for specific tests, especially in relation to children.
It is recommended that all tests are overseen by the patients GP and/or endocrinologist. This is because it is important that a doctor has carried out a full examination of the patient and talked to them face-to-face to ensure that they can properly interpret the results of any tests. The advantage of a professionally collected sample , eg, blood from a vein, is that enough is taken to allow double-checking of extreme results, repeating the analysis after dilution, investigating possible human or biological interference, allowing additional tests to be carried out if required without the delay and discomfort of taking another sample.
Some internet laboratories are acceptable, but the small volume of self-taken samples creates limitations. With hormones, it is often best to measure more than one at once in order to get the full-picture.
It can be difficult for internet laboratories without full knowledge of individual medical details, for example, the drugs being taken, to appreciate the significance of the results, or fully interpret them.
It is important to take care when comparing results from different laboratories because significant variation can arise from differences in the measurement technology.
Symptoms And Potential Complications
Imbalances in female hormones can have far-ranging effects on the body, producing a variety of physical, emotional and cognitive changes. These changes can cause symptoms that may include:
- Menstrual cycle changes, including shorter or longer times between periods, and periods that are longer, shorter, heavier or lighter than normal.
- Hot flashes and night sweats.
- Insomnia and other sleep disturbances
- Diminished sex drive
- Unexplained weight gain, especially in the abdominal area, hips and thighs
- Skin changes, such as thinning, dryness and wrinkling
- Dry, brittle hair
Female hormone imbalance can increase a womans risk of a number of diseases and health problems. Among the most serious of these is heart disease, with risk increasing as estrogen levels decrease. Women with hormonal imbalances are also at greater risk for osteoporosis, since low levels of estrogens can interfere with the absorption of calcium and other nutrients essential to the maintenance of bone health and density.

Diagnosis Of Womens Hormonal Imbalance
Since the symptoms of female hormone imbalance are also common signs of a number of other diseases and health conditions, women experiencing them should see a physician for a thorough physical examination. If other underlying medical conditions are ruled out, hormone level testing is the next step. Hormone levels can be measured through saliva testing and/or blood tests. Establishing an accurate diagnosis of hormone imbalance may require several tests, done at intervals, as hormone levels fluctuate throughout a womans menstrual cycle and may change greatly from one day to another.
Are There Any Other Factors That Might Affect The Outcome Of The Test
The blood level of several hormones changes significantly with the time of day. For example, cortisol and testosterone are highest in the early morning. The response of glands to hormones given to patients during dynamic tests may also show this diurnal variation for example, the response of the adrenal gland to synacthen is higher in the morning.
The day of the menstrual cycle also has a major impact on hormone levels. In general, blood samples are best taken in the first half of the cycle when normal and abnormal hormone levels are more clearly separated. However, progesterone may be deliberately measured on day 21 in the middle of the second half to see if ovulationhas occurred.
It is human nature to ignore doctors advice. Not taking medication as prescribed, or taking extra the week before the test in an effort to make up for doses missed previously, will give misleading results and the patient may miss out on a full return to health.

What Do The Results Mean
If your estradiol or estrone levels are higher than normal, it may be due to:
- Early puberty in girls delayed puberty in boys
If your estradiol or estrone levels are lower than normal, it may be due to:
- Primary ovarian insufficiency, a condition that causes a woman’s ovaries to stop working before she is 40 years old
- Turner syndrome, a condition in which a woman’s sexual characteristics don’t develop properly
- An eating disorder, such as anorexia nervosa
- Polycystic ovary syndrome, a common hormone disorder affecting childbearing women. It is one of the leading causes of female infertility.
If you are pregnant and your estriol levels are lower than normal, it may mean your pregnancy is failing or that there is a chance your baby might have a birth defect. If the test shows a possible birth defect, you will need more testing before a diagnosis can be made.
Higher levels of estriol may mean you will be going into labor soon. Normally, estriol levels go up about four weeks before you start labor.
If you have questions about your results, talk to your health care provider.

Is Blood Testing The Best Way To Check Your Hormones
In todays blog, were going to go through what blood testing is good for, what its not good for and how you can use the results to help you cure your hormonal acne.
Blood testing is great to pinpoint a few different things.
The number one thing is pathology. Thats diseases. Its when things have gone seriously wrong in your body or you have a major hormone imbalance. Blood testing is great for picking these things up.
Blood testing is also great for identifying nutritional deficiencies. Things like vitamin and mineral deficiencies, which well look at some results in a minute and see what they look like.
But when we think about hormonal acne and PCOS though, blood testing is only going to pick up hormone imbalances if theres a big problem. But, the one area blood testing is always good for it is when we want to look at baseline hormone levels.
In women, this is at the beginning of your menstrual cycle . This is when its good to use a blood test because you can get your baseline hormonal values and see if theres any significant dysfunction there.
At baseline, the hormones you want to look at are FSH, LH, Estradiol and Progesterone . At the beginning of your cycle, the progesterones always going to be low, which is why you see it quite a low in the above results. This is because progesterone doesnt come up until after you ovulate. So early in your cycle ovulation hasnt occurred yet so it will naturally be low.
Thyroid Testing With Blood
The most common way to test thyroid function, and the test that is considered the gold standard is a blood test, but it is important that you get a complete thyroid test and not just the TSH test.
The complete thyroid test includes:
- TSH This is important because we want to see what messages the brain is sending to the thyroid.
- Free T4 This is the storage form of the thyroid that is made by the thyroid gland in response to TSH, this is also the form of the thyroid that is usually prescribed in medications but some people have a problem converting T4 to T3.
- Free T3 This is the metabolically active form of thyroid hormone which makes it the most important thyroid hormone to be optimal. T4 to T3 conversion happens throughout the body.
- Reverse T3 This is an inactive form of thyroid hormone, important to test because high levels indicate adrenal issues or high levels of inflammation.
- Thyroid antibodies This indicates if you have an autoimmune thyroid problem, also important to test because often this will rise well before there is a problem with the other thyroid hormones.
You can still have normal TSH and even normal T4 levels but have a low thyroid function, check out this video below and I explain the importance of the complete thyroid test, and show a number of different examples of perfect TSH levels but low levels of the metabolically active T3. Note the measurement units in the U.S are different but the principle is still the same.
Reasons To Get Your Hormone Levels Checked Out
People have varying outlooks regarding becoming older. Your attitude towards advancing years will probably have much to do with the condition of your overall health. If you still feel agile and look comparatively young, you most likely wont care too much about your chronological age. However, for many people, getting older comes with a minefield of incommodious health issues.
If you are older, and your overall health is diminishing, consider talking to your GP about getting a blood test to determine your hormone levels. Here are ten worthy reasons why it is a good idea to get your hormone levels evaluated:
Weight gain is a common symptom of plummeting hormone levels in both men and women. Low testosterone can cause men to develop a stout abdomen and surplus fat in the pectoral area. It can also cause the loss of muscle mass. Laboratory research has shown that in female mammals, dwindling estrogen levels can lead to lethargy and general weight gain. Carrying too much weight can cause other health complications, such as diabetes, hypertension, and cardiovascular disease.
If low levels of sex hormones, like testosterone and estrogen, have caused you to feel sluggish, you may not have the energy to exercise as much as youd like. Exercise is of vital importance to your overall health. It can safeguard you against a multitude of physical ailments and diseases. It is also excellent for your mental health, and it keeps your body looking and feeling young.
