DHEA, (Dehydroepiandrosterone),Unconjugated

 $18.49

This test measures the levels of DHEA, a hormone that plays a role in developing male secondary sexual characteristics but is present in both men and women. It's particularly useful for diagnosing conditions like congenital adrenal hyperplasia and helps in identifying the source of excessive androgens, which could be due to conditions like polycystic ovarian syndrome (PCOS) or adrenal tumors.

Diabetes Risk Panel without Score

 $25.49

To assist with control of blood glucose levels, the American Diabetes Association (ADA) has recommended glycated hemoglobin testing (HbA1c) twice a year for patients with stable glycemia, and quarterly for patients with poor glucose control. Interpretative ranges are based on ADA guidelines.

  • Glucose Your blood sugar level at the time of the test — a core marker for diagnosing and monitoring diabetes and metabolic health.
  • Hemoglobin A1c (HbA1c) Reflects your average blood sugar over the past 2-3 months, based on how much sugar has attached to your hemoglobin. Key marker for diabetes diagnosis and monitoring.
  • Total Cholesterol The combined measure of all cholesterol in your blood — HDL, LDL, and other lipoproteins together. A foundational marker of cardiovascular risk.
  • Triglycerides A type of fat in your blood used for energy storage. Elevated levels are linked to increased cardiovascular risk and often reflect diet, weight, or metabolic health.
  • HDL Cholesterol The 'good' cholesterol that helps remove excess cholesterol from your bloodstream. Higher levels are generally linked to lower cardiovascular risk.
  • LDL Cholesterol (by calculation) The 'bad' cholesterol that can build up in artery walls. A core marker used to assess cardiovascular disease risk.
  • Non-HDL Cholesterol Total cholesterol minus HDL — capturing all the potentially artery-clogging ('bad') cholesterol particles in one number.
  • Total Cholesterol / HDL Ratio Compares your total cholesterol to your HDL ('good') cholesterol, offering a quick snapshot of cardiovascular risk balance.

Dihydrotestosterone, Free, Serum

 $35.49

This test measures the level of dihydrotestosterone (DHT) in the blood, which is crucial for diagnosing conditions like 5-alpha-reductase deficiency that affects male sexual development. It's also used to monitor the effectiveness of treatments that impact androgen levels. DHT is a key androgen involved in the development of male external genitalia, prostate growth, and skin health. It's mainly produced from testosterone through the action of 5-alpha-reductase in tissues.
