FSH and LH are produced by the pituitary gland to control the production of sex hormones including testosterone and estrogen, and sperm and egg cells. They are both important in diagnosing primary or secondary hypogonadism, infertility, or potential pituitary adenomas.

This lab test panel includes main blood test makers involved in hair loss in women and men: Complete Blood Count (CBC)- Can detect potential low hemoglobin and infections that can lead to hair loss. Ferritin- Low ferritin, an iron storage protein, has been linked to hair loss and slow down of hair growth. Iron and Total Iron Capacity (TIBC)- Low iron anemia has been linked to hair loss.  Hyperandrogenism: Excessive male hormones (androgens): Total Testosterone (LC/MS), Free Testosterone (Equilibrium Ultrafiltration), DHEA-S, Dihydrotestosterone (DHT)  Hypothyroidism and Hyperthyroidism: Thyroid Stimulation Hormone (TSH), Free Triidothyronine (Free T3)

 Progesterone is a female hormone important for the regulation of ovulation and menstruation. It is also present in men in smaller concentrations. Progesterone is a steroid hormone that plays numerous roles within the human body. It is crucial to the production of sex hormones and corticosteroids, as well as playing a role as a neuro-steroid (brain function). 

A blood pregnancy test is a medical test used to determine if a woman is pregnant by detecting the presence of the hormone hCG in her blood. Shortly after the fertilized egg implants into the uterine lining, the developing placenta produces the hormone known as hCG. This test is the Quantitative hCG test (also known as a beta hCG test) and measures the specific amount of hCG present in the blood. It can help determine how far along a pregnancy is, monitor the progress of the pregnancy, and detect potential issues like an ectopic pregnancy or a miscarriage.

Blood pregnancy tests are more sensitive than over-the-counter urine pregnancy tests and can detect pregnancy earlier – as soon as 6 to 8 days after ovulation.

To find out if sperm count is normalized in men using hCG plus TRT, several studies have found that 17OH-P blood level is correlated to intratesticular testosterone (ITT) required for the testicles to make sperm, so testing for this hormone could not only save time while optimizing HCG dose/frequency but also eliminate the need to perform testicular aspirations, a very difficult procedure to do. Sperm count does not stabilize until 6-8 weeks after starting hCG plus TRT, so knowing your 17OH-progesterone blood level can give you a quick way to determine if your hCG dose and frequency is adequate before your first follow-up semen analysis after 8 weeks.

This is the most accurate progesterone test that has no potential interactions and can detect very low levels in men and women.  Since it is performed with liquid chromatography and mass spectrometry, results are available after 5 to 7 business days.
