Testosterone is a male sex hormone produced in a woman’s ovaries in small amounts as well. Combined with estrogen, the female sex hormone, testosterone helps with the growth, maintenance, and repair of a woman’s reproductive tissues, bone mass, and human behaviors.

The testosterone-cortisol ratio is a valuable tool for understanding the balance between anabolic and catabolic processes in your body. Monitoring and optimizing this ratio can enhance physical performance, ensure adequate recovery, and maintain overall hormonal health. Whether you're an athlete, a clinician, or a fitness enthusiast, the T/C ratio offers crucial insights into your body’s physiological state and responses to various stressors.

Tetanus is a serious disease caused by the toxin from Clostridium tetani bacteria. The toxin makes its way into the nervous system and causes muscle spasms and rigid muscles.

If you have been vaccinated for tetanus in the past, this test should show that you have enough antibodies against the disease. If your levels are too low, you should receive a booster vaccine. The test will be repeated after at least a month. Several variations of the tetanus vaccine are available. The vaccine is recommended as a series in childhood. A booster vaccine is recommended every 10 years for teens and adults.

If you've never had a tetanus vaccine or been exposed to tetanus, you'll get vaccinated. You may return later to have your tetanus antibody levels checked to make sure the vaccine is working.

Stay Protected with Tetanus Vaccines: Essential Information

Tetanus is a serious infection caused by Clostridium tetani bacteria, but the good news is that vaccines are available to prevent it. In the United States, three types of vaccines provide protection against tetanus, along with other diseases:

• Diphtheria, Tetanus, and Pertussis (DTaP) Vaccines
• Tetanus, Diphtheria, and Pertussis (Tdap) Vaccines
• Tetanus and Diphtheria (Td) Vaccines

Who Should Get Which Vaccine?

• Babies and children under 7 years old receive the DTaP vaccine.
• Older children and adults receive the Tdap and Td vaccines.

Tetrachloroethylene (PCE) is a chemical widely used in the dry cleaning of clothes and fabrics and in metal degreasing. It is also a prevalent drinking water contaminant.

The GI-MAP includes results for detection of H. pylori antibiotic resistance genes. If an antibiotic resistance gene is present, then that class of antibiotics is designated POSITIVE for antibiotic resistance. A positive result for the presence of resistance genes for a given antibiotic indicates that the antibiotic is not an ideal choice for an antibiotic protocol. Since microbes can rapidly share DNA under stress, the presence of antibiotic resistance is reason enough to avoid that drug class.

Tetradecanoylcarnitine (C14) is a long-chain acylcarnitine formed during the transport and breakdown of 14-carbon fatty acids in the mitochondria. It reflects how efficiently long-chain fats are activated, transported, and oxidized for energy. C14 levels provide insight into mitochondrial beta-oxidation, metabolic flexibility, and the body’s capacity to use fat as a fuel source.

This is one of the three cortisol metabolites. The total some of the three cortisol metabolites gives us a good indication of the overall cortisol production in your body. 

Two of the 3 metabolites are the active form of cortisol (THF). The other metabolite is in the inactive form cortisone.

This particular marker (a-THF) hence is an active cortisol metabolite.

Tetrahydrocortisol (THF) is a metabolite of cortisol, the body’s main stress hormone produced by the adrenal glands. After cortisol circulates through your body and performs its functions—regulating energy, blood sugar, and the stress response—it is broken down in the liver into several metabolites, including THF and tetrahydrocortisone (THE).

Measuring THF in urine provides insight into how efficiently your body is metabolizing and clearing cortisol, offering a more complete picture of adrenal activity and stress hormone balance over time.
