Hormones

DHEA, produced by the adrenal glands, serves as a precursor to sex hormones. Its saliva measurement reflects active hormone levels, indicating the body's immediate DHEA production. This assessment helps in evaluating adrenal function, aging processes, and risk for chronic diseases....

DHEA

DHEA-S, the sulfate form of DHEA, is more stable and abundant in blood. Blood measurement of DHEA-S provides a longer-term view of DHEA levels, useful for assessing hormonal balance, adrenal function, and aging-related changes over time....

DHEA-S

Estrogen is a key female hormone, also present in men, crucial for developing and regulating the female reproductive system and secondary sex characteristics. In women, it manages the menstrual cycle and affects the reproductive tract, skin, and bones. In men, it's involved in libido, erectile function, and sperm production. Produced mainly in women's ovaries and in men's testes, estrogen levels fluctuate significantly during puberty, menstrual cycles, pregnancy, and menopause. Imbalances can lead to health issues like menstrual irregularities and mood swings....




Estrogen (estradiol)

The Estrogen/Progesterone ratio is a crucial indicator of hormonal balance in the body, particularly in women. Estrogen and progesterone are key hormones in female reproductive health, and their balance is essential for regular menstrual cycles, fertility, mood regulation, and overall well-being. An optimal ratio ensures a harmonious interplay between these hormones, while an imbalance can lead to various health issues. This ratio changes throughout the menstrual cycle and can be affected by factors like age, lifestyle, and health conditions....

Estrogen/Progesterone ratio

Free Triiodothyronine (fT3) is one of the two primary thyroid hormones, playing a crucial role in regulating metabolism, heart rate, and body temperature. Unlike total T3, fT3 represents the unbound hormone available for immediate use by the body, making it a critical indicator of thyroid function....

Free T3 (fT3)

Melatonin is a hormone primarily produced by the pineal gland in the brain. It plays a crucial role in regulating the body's circadian rhythms, including the sleep-wake cycle. Melatonin levels typically rise in the evening, peak during the night, and decrease by morning, signaling the body to prepare for sleep. It's also involved in other physiological processes, including immune function and antioxidant activity....




Melatonin

Progesterone is a hormone crucial for the female reproductive system, mainly produced in the ovaries after ovulation. It prepares the uterus for potential pregnancy and maintains it if pregnancy occurs; if not, its levels drop to trigger menstruation. Progesterone also affects sexual desire, mood regulation, and bone strength. In pregnancy, it's produced by the placenta to support the pregnancy and prepare for breastfeeding. Men have lower levels of progesterone, involved in sperm development....




Progesterone

Prolactin is a hormone produced by the pituitary gland, primarily associated with lactation in females. It plays a role in fertility, regulates the immune system, and impacts sexual satisfaction. High levels can cause symptoms like irregular periods or infertility, while low levels might affect milk production post-pregnancy....

Prolactin

Testosterone is a hormone primarily associated with male sexual development and health, though it's also important in women. In men, it's produced mainly in the testes and is crucial for developing male reproductive tissues, promoting secondary sexual characteristics like muscle mass and body hair, and influencing libido and mood. Women produce testosterone in smaller amounts in the ovaries and adrenal glands, where it contributes to bone strength, ovarian function, and libido....

Testosterone (total)

Luteinizing Hormone (LH) is a crucial hormone in both men and women, produced by the anterior pituitary gland. In women, LH plays a vital role in ovulation and the maintenance of the menstrual cycle. It triggers the release of an egg from the ovary and stimulates the production of progesterone. In men, LH stimulates the production of testosterone by the testes. Balanced LH levels are essential for reproductive health and hormonal balance in both sexes....




Luteinizing Hormone

Thyroid Stimulating Hormone (TSH) is produced by the pituitary gland to regulate thyroid function. It signals the thyroid to produce thyroid hormones, which are crucial for metabolism, energy, and growth. TSH levels help diagnose thyroid disorders, indicating whether the thyroid is functioning properly....

Testosterone (free)

Free Thyroxine (fT4) is another key thyroid hormone, essential for metabolism, brain development, and bone health. It acts as a precursor for fT3. Measuring fT4 helps assess thyroid function, as it shows the hormone directly produced by the thyroid gland and available for conversion to fT3....

Free T4 (fT4)

Cortisol, often recognized as the primary stress hormone, is synthesized by the adrenal glands, which are triangular-shaped organs situated on top of each kidney. This vital hormone plays a crucial role in orchestrating a multitude of physiological processes within the human body. Among its diverse functions, cortisol is intricately involved in the regulation of metabolism, modulation of immune responses, and orchestration of the body's reaction to stressors....

Cortisol

Follicle-Stimulating Hormone (FSH) is a crucial reproductive hormone in both men and women, produced by the pituitary gland. In women, it stimulates the ovaries to mature egg follicles; in men, it aids in the production of sperm. FSH levels fluctuate throughout a woman's menstrual cycle and are integral to fertility and reproductive health....

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

Absolutely perfect, results came after few days and finally after a lots of times visited GP, we finally know why my son has eczema - he is allergy to carrot. Thanks a lot.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.

Individuals with symptoms of thyroid dysfunction, family history of thyroid disease, or those undergoing treatment for thyroid disorders should test their TSH levels. It&rsquo;s also recommended for people experiencing unexplained weight changes, fatigue, or mood fluctuations.

Who would benefit from testing their TSH levels?

Underactive Thyroid (Hypothyroidism):
<ul>
 <li>
 <ul>
 <li>Fatigue and sluggishness</li>
 <li>Unexplained weight gain</li>
 <li>Dry skin and hair</li>
 <li>Sensitivity to cold</li>
 <li>Constipation</li>
 </ul>
 </li>
</ul>
Overactive Thyroid (Hyperthyroidism):
<ul>
 <li>
 <ul>
 <li>Unintended weight loss</li>
 <li>Increased heart rate</li>
 <li>Anxiety and nervousness</li>
 <li>Heat intolerance</li>
 <li>Insomnia</li>
 </ul>
 </li>
</ul>

What are symptoms of low or high TSH levels?

Measuring only TSH can miss subtler forms of thyroid dysfunction. TSH levels can be normal while thyroid hormones (T3 and T4) are not, which is why testing T3 and T4 alongside TSH provides a more comprehensive view of thyroid health.

Why is it not enough to measure only TSH?

<ul>
 <li>High TSH Levels:&nbsp;Indicate an underactive thyroid (hypothyroidism), where the thyroid gland isn&rsquo;t producing enough hormones, prompting the pituitary gland to release more TSH.</li>
 <li>Low TSH Levels:&nbsp;Suggest an overactive thyroid (hyperthyroidism), where the thyroid produces too many hormones, leading to reduced TSH production by the pituitary gland.</li>
</ul>
