What is Adrenal Fatigue?

The adrenal glands maintain and keep the body’s stress hormones in balance. If someone is under pressure and stress the adrenal glands become diminished which may causing a decrease in the amount of steroid hormones in the body, particular cortisol.

  • Feeling overwhelming or daunting
  • Need coffee or stimulant to get going in the morning

How accurate is the Saliva Test?

The published studies have shown that a saliva test is much more accurate than a serum test. It is a reliable marker of testosterone bioavailability, principally for very low levels, (Serum tests are often unreliable in this area), Cortisol and other adrenal hormones. Saliva testing also can measure hormones such as testosterone in women or children and estrogen in men.

Which Hormones also called Longevity?

Hormone DHEA is known as longevity hormone.

Why Measure With Saliva?

  • Accurate
  • Reliable, Valid in everyday context
  • Easy to collect at home
  • Safe to handle
  • Non-invasive

What is a benefit of Salivary Hormones?

More representative of bioavailable hormone in saliva compared to total serum hormone.
A salivary hormone test is a comprehensive hormone test, which can reveal many clues about the current health status, which is easy and simple to collect the specimen without using needles, and can be collected in privacy at home.

Why hormone in saliva is better than testing hormones in blood or serum?

Salivary Testing is more accurately than blood. Salivary hormone tests can test more accurately than blood tests for the ‘free or available’ level of sex hormones plus a few other very important steroid hormones. In blood, most of these hormones are bound to large protein molecules, which effectively make them unavailable to the cells. Only the small percentage of these hormones not bound to protein molecules (estimated to be less than 5%) are able to move out of blood vessels and be used by cells.
A salivary hormone test is a comprehensive hormone test, which can reveal many clues about the current health status, which is easy and simple to collect the specimen without using needles, and can be collected in privacy at home.

Why test saliva for hormones?

  • Saliva hormone testing is non-invasive and easy to collect at the convenience and privacy of home.
  • Inexpensive and economical to know the hormones imbalance
  • Saliva hormones reveal the healthy life style.
  • Blood collection is sometimes very stressful while saliva collection is simple.
  • Saliva sample collections can be timed precisely, which is critical for some hormones specially early in the morning and evening.
  • Multiple saliva collections can be possible in a single day to evaluate daily fluctuation.
  • Saliva testing is an accurate, flexible tool for adjusting and monitoring hormone replacement therapy (HRT).
  • Saliva specimen can be transported easily from anywhere through-prepaid mailers. This convenience is possible because saliva hormones are stable at room temperature for at least 3 weeks.
  • Saliva testing measures the levels of the free, bio-available hormones – those hormones which move freely into cells and carry out the body’s critical jobs.

Do the Low levels of Estrogen, Progesterone and Testosterone can result to low libido?

Experts say that loss of desire and low sex drive may be directly related to lower estrogen, progesterone, or testosterone levels, which often happens during menopause. Low sex derives and libido is the most common sexual complaint by women.
Hormonal imbalance can occur in young age

What is the Role of Testosterone in women?

Hormonal imbalance in women causes reduced ovarian function, or a hysterectomy. This is due to the low amount of testosterone a woman produces, especially in post menopause. Generally Testosterone hormone is mainly considered a hormone for men, but it also serves important purposes for women. In terms of libido, testosterone for women serves to heighten sexual response and orgasms. As a result, low testosterone causes a loss of libido.

What is the function of Progesterone and Estrogen in women?

Progesterone naturally decreases production during perimenopause; this can result in an estrogen dominance, which effectively causes low sex derive and low libido in women. This hormonal imbalance often causes vaginal dryness, vaginal atrophy (a loss of muscle tension), and decreased clitoral sensitivity. The increase level of estrogen also causing mood swings, weight gain, and fatigue, body ache add to the problem. Too little estrogen causes similar vaginal problems.

What is Low Libido in Women?

The hormonal imbalances found in menopause, perimenopause and post menopause in women commonly results in the decline in sexual drive or low libido. The main hormone responsible for low libido in women is progesterone, testosterone, and estrogen.

When does Testosterone Levels Begin to Decrease?

Testosterone levels are at the highest during puberty and adolescence. However, testosterone levels begin declining after the age of 30. This decline leads to many changes in your body. It will results in physical and mental changes in the body. Testosterone begins declining after the age of 30 and research indicates that in an average man generally lose 1% of testosterone a year. This decline is testosterone levels is gradual but on average by the time you reach 40 you have already lost 10% of this hormone and you can feel the effects more sharply.

Testosterone levels in American men have been declining steadily over the past two decades. Ref: In a 2006 studies, published in the Journal of Clinical Endocrinology and Metabolism.

Does Low sex derives is the symptoms of low testosterone level?

Low sex derives and low libido in men is a common symptom of Andropause and Testosterone Imbalance.

What is the function of Testosterone?

Testosterone also is the hormone that controls sexual function in men. Testosterone is known for its ability to increase libido and sex derive. Testosterone also plays a key role in keeping men’s bones dense and strong and in building muscle mass. Low testosterone levels also contribute to low sperm count.

Does eating interfere with test results?

Food can create a more viscous or “junky” specimen and any particles can interfere with the test result. Good sample is the first step for achieving the accurate and reliable test results. The ingestion of food is not the issue; it is the creation of as “clean” a specimen as possible. While there are laboratory procedures to eliminate as much of this type of interference as possible, it is best to submit a sample taken when food residue is not in the mouth.

Why it is necessary to complete the symptom questionnaire or request form?

This is very useful for the doctor interpreting the test results takes symptoms into consideration as well as laboratory result. The same thing applies to the section of the requisition where we request information on hormones the patient is taking.

Why should cycling women collect their sample only on days 19-21 of their cycle period?

These days will reflect the luteal phase, which is the appropriate time to measure both progesterone (which should be at its peak) and estradiol in order to calculate the most accurate ratio between the two.

Why is there a difference in the instructions for sublingual and topical hormone use?

Sublingual hormones are detected in saliva for a longer period than topical hormones. If these instructions are not followed, a true therapeutic level will not be reflected.

Why we don’t apply facial lotions or creams during saliva collection?

Many “anti-aging/wrinkle” creams contain the very hormones that we test. It is easy to contaminate a specimen by direct contact with the straw or tube or by absorption into the body, thus altering the results to an inaccurate higher level.

Why do we collect four tubes if only one test is ordered?

All the samples collected in 4 tubes throughout the day in different intervals such as morning, noon, evening, and night, pool together equal amount from each tube and transfer into the 5th tube, which is used for testing such as Estradiol, DHEA, Testosterone, and Progesterone. This process ensures a more accurate overall average of the hormone level.

Why do we collect 4 samples for cortisol?

Cortisol fluctuates and we like to measure ups and downs, to check the diurnal pattern.

When saliva sample will be taken?

Before brushing teeth or one hour later after meal.
