Health metricBaselineFollow-up
Hormones
Testosterone, free and total
Total testosterone by mass spectrometry and free testosterone by equilibrium dialysis, the reference method for the unbound fraction.
SHBG
Sex hormone-binding globulin. It binds testosterone and estradiol, and it helps explain how total and free testosterone relate.
Estradiol
The main form of estrogen. Men make some of it from testosterone. In women, the level changes across the menstrual cycle.
Blood health
Complete blood count
Red cells, hemoglobin, hematocrit, white cells and platelets. Clinicians watch hematocrit during testosterone therapy.
Metabolic health
Comprehensive metabolic panel
Glucose, electrolytes, kidney markers such as creatinine, and liver markers such as ALT and AST.
Heart health
Lipid panel (Cardio IQ)
Total cholesterol, LDL, HDL and triglycerides, with cholesterol ratios.
Prostate
PSA, free and total
Total prostate-specific antigen, plus the share that circulates unbound. The free fraction adds context to the total.
Thyroid health
TSH
A pituitary hormone that signals your thyroid to make thyroid hormones.
Free T3
The active thyroid hormone, measured in its unbound form.
Free T4
The main hormone your thyroid releases, measured in its unbound form.

How is my blood collected?
Lab staff draw blood from a vein at a Quest patient service center. You can book a time or walk in.
Do I need to fast?
Your lab order lists any fasting or timing instructions for your tests. Follow those instructions, and ask your care team before you change a prescribed medication.
Where will I see my results?
Your results come into your Rebody account, next to any bloodwork you already keep there.
Is this a diagnosis?
No. A lab panel measures markers in your blood. A clinician interprets results with your history and symptoms, and reference ranges vary by lab and method.
Can a phlebotomist come to me?
Yes, for the TRT panels. An at-home phlebotomist visit is available for an added fee. The Advanced and Complete panels are drawn at a Quest patient service center.
Does ordering labs start testosterone therapy?
No. Lab results help a clinician decide on care. Treatment decisions come from a clinician who reviews your results and health history.
