This panel contains:

• Fasting Insulin
• Comprehensive Metabolic Panel (Includes Glucose)

Glucose and insulin can be used to calculate HOMA-IR (Homeostatic Model Assessment of Insulin Resistance)

This PCT after cycle panel is designed to measure the health and recovery of the Hypothalamic-Pituitary-Testicular Axis (HPTA) after attempting to normalize it spontaneously or with the use of Post-Cycle Therapy (PCT) . PCT is prescribed by some physicians for men who stop testosterone replacement therapy (TRT) or other androgens. Fasting is required for CMP (glucose test).

This TRT basic lab test panel includes essential tests (CBC, CMP, ultrasensitive estradiol, and total & free testosterone) to monitor treatment in men on that have been testosterone replacement therapy for a few months. Test included:

• CBC (White and red blood cells, hematocrit, etc)
• CMP (glucose, liver & kidney function, etc)
• Estradiol Ultra Sensitive
• Total Testosterone (LC/MS)
• Free Testosterone (Equilibrium Dialysis)

Fasting is required for proper glucose testing as part of CMP.

This test panel includes most tests needed to more deeply explore the possibility of hypothyroidism and/or Hashimoto's disease diagnosis. It includes: TSH, Free T3, Free T4, Reverse T3, Thyroglobulin Antibody and Thyroid Peroxidase Antibody (Anti-TPO). If you are taking biotin, please stop it 72 hours before the blood draw since it may interfere with hormone blood tests. A study found that TSH was suppressed in all subjects after food, so fasting may be suggested although it is not reqired by Quest. Free T4 and Free T4 values did not change significantly after eating. NOTE: Reverse T3 is analyzed using a specific technique called liquid chromatography/tandem mass spectrometry (LC/MS-MS). There's a special place in the U.S. where these precise machines needed for LC/MS panels run only on two specific days a week. So, sometimes the clock ticks a bit while we wait for samples to return from their initial collection points. Results may take 7 business days.

The Cardio IQ® Insulin Resistance Score (IR), which uses fasting insulin and C-peptide measurements to estimate a person's likelihood of having insulin resistance. It eliminates the need for multiple samples and reduces the chance of errors that can occur with some other tests.

Having a high score (indicating a greater probability of insulin resistance) was linked to an increased risk of developing type 2 diabetes, even after accounting for other risk factors. 

An IR score of <33 suggests that an individual has normal insulin sensitivity.
A score of 33 to 66 suggests that an individual has >4-fold greater odds of having IR compared with an individual with a score <33 .
A score >66 suggests that an individual has >15-fold greater odds of having IR compared to an individual with a score

Fasting Required for 10-12 hours. Water only.

The most complete of all blood test panels for men that include: Total and Free Testosterone, Ultra Sensitive Estradiol, IGF-1, Prolactin, DHT, DHEA-S, PSA, SHBG, Lipids, CBC, CMP, and Thyroid Function (TSH, Free T3, Free T4).
