Why get a comprehensive lab panel?
A lab panel gives you and your provider a clear starting point. Many of our clients use it as a yearly check-in. Others get one before starting testosterone therapy, hormone therapy or other longevity services, so their provider can see where they are before anything changes, and then compare later results to that baseline.
We offer a men’s panel and a women’s panel. Each costs $195 and covers more than 40 results from one quick blood draw. The core tests are the same; the hormone tests differ, as noted below. You don't need to fast.
Everything in the Onus lab panel
- Comprehensive metabolic panel (CMP): blood sugar, kidney and liver markers, electrolytes and proteins
- Complete blood count (CBC) with differential: red cells, white cells and platelets
- Hormones: total testosterone, free testosterone, estradiol, DHEA-sulfate, progesterone (women) and PSA (men)
- Hemoglobin A1c: average blood sugar over the past 2–3 months
- Vitamins: vitamin D (25-hydroxy) and vitamin B12
Here's what each part looks at, in plain English.
Comprehensive metabolic panel (CMP)
The CMP is one of the most commonly ordered blood tests. It includes:
- Glucose: the amount of sugar in your blood at the time of the draw.
- Kidney markers: BUN (blood urea nitrogen) and creatinine are waste products your kidneys filter out. eGFR is an estimate of how well your kidneys are filtering, calculated from creatinine. The BUN/creatinine ratio compares the two.
- Electrolytes and minerals: sodium, potassium, chloride, carbon dioxide (bicarbonate) and calcium, which help regulate fluid balance, nerves and muscles.
- Proteins: total protein, albumin and globulin. Albumin is made by the liver; globulins include many of the proteins your immune system uses.
- Liver markers: bilirubin, alkaline phosphatase, AST and ALT.
Complete blood count (CBC) with differential
The CBC looks at the three main types of cells in your blood.
- Red blood cells: RBC count, hemoglobin (the protein that carries oxygen), hematocrit (the share of your blood made up of red cells), and MCV, MCH, MCHC and RDW, which describe the size of your red cells and how much hemoglobin they carry. Hematocrit is one of the values providers commonly check during testosterone therapy.
- White blood cells: a total WBC count plus a differential that breaks it down into neutrophils, lymphocytes, monocytes, eosinophils, basophils and immature granulocytes, as both a percentage and an absolute count.
- Platelets: the cells that help your blood clot.
Hormones
- Total testosterone: all of the testosterone in your blood. Testosterone matters for women as well as men.
- Free testosterone: the portion that isn't bound to proteins in the blood.
- Estradiol: the main form of estrogen, measured in both women and men.
- DHEA-sulfate: a hormone made mostly by the adrenal glands that the body uses to make other hormones.
- Progesterone (women): a key hormone in the menstrual cycle and in perimenopause.
- PSA, total (men): prostate-specific antigen, a protein made by the prostate. Providers commonly check it for men on, or considering, testosterone therapy.

Hemoglobin A1c and vitamins
- Hemoglobin A1c: reflects your average blood sugar over the past 2–3 months, so it gives a longer view than a single glucose reading.
- Vitamin D, 25-hydroxy: the standard blood test for vitamin D levels.
- Vitamin B12: the level of vitamin B12 in your blood.

A note on reading your results
Lab results don't diagnose anything on their own. Reference ranges vary by lab, and a result outside the range isn't always a problem, just as a result inside it isn't always the full picture. A licensed provider looks at your results together with your health history and goals. This article is general information, not medical advice.
