Quick Facts
- Sample: Blood
- Fasting: No fasting is required. Avoid ejaculation, strenuous exercise, and biotin supplements for 72 hours before testing; wait at least six weeks after a prostate biopsy before PSA testing.
- Turnaround: 7 to 10 days (may take longer based on weather, holiday, or lab delays)
What's Included
Complete Blood Count (CBC) with Differential and Platelets
- White Blood Cells (WBC): Your body's primary defense against disease, helping fight infection.
- Red Blood Cells (RBC): Carries oxygen and carbon dioxide to and from your cells.
- Hemoglobin: The protein inside red blood cells that transports oxygen through your bloodstream.
- Hematocrit: The percentage of your blood made up of red blood cells.
- Neutrophils: The most common white blood cell type, created to combat infection and inflammation.
- Absolute Neutrophils: Measures the actual number of neutrophils in your blood.
- Lymphocytes: B-cells and T-cells that fight bacteria and other pathogens.
- Lymphs (Absolute): The absolute number of lymphocytes, calculated from your WBC count and lymphocyte percentage.
- Monocytes: Work alongside neutrophils to fight infection and clear away damaged cells.
- Monocytes (Absolute): The absolute number of monocytes in your blood.
- Eosinophils (Eos): White blood cells activated in response to allergies and certain infections.
- Eos (Absolute): The absolute number of eosinophils in your blood.
- Basophils: Help detect infections early and play a role in wound healing and allergic responses.
- Baso (Absolute): The absolute number of basophils in your blood.
- Immature Granulocytes: A measure of immature white blood cells present in your differential.
- Immature Grans (Abs): The absolute number of immature granulocytes in your blood.
- Mean Corpuscular Hemoglobin (MCH): The average amount of hemoglobin within a red blood cell.
- Mean Corpuscular Hemoglobin Concentration (MCHC): The average hemoglobin concentration percentage within a red blood cell.
- Mean Corpuscular Volume (MCV): The average size of your red blood cells.
- Red Cell Distribution Width (RDW): Measures the amount of variation in red blood cell volume and size.
- Platelet Count: Blood cell particles involved in forming clots.
Prostate-Specific Antigen (PSA), Serum
- Prostate Specific Ag: Measures PSA, a protein produced by the prostate gland. Elevated levels may relate to prostate conditions such as prostatitis or benign prostatic hyperplasia (BPH), though further evaluation is needed to determine the cause.
Testosterone, Free Direct with Testosterone Total
- Testosterone, Free: Measures unbound testosterone, the active form of the hormone, using a direct method.
- Testosterone, Total, MS: Measures the total amount of testosterone (bound and unbound) in your blood using mass spectrometry.
Lab-specific note (LabCorp only): Any Testosterone Free (Direct) or Total Testosterone result exceeding 1500 will be reported as ">1500."
Benefits

FAQ
1. What is the purpose of this test?
This panel combines a Complete Blood Count (CBC) with Differential and Platelets, a Prostate-Specific Antigen (PSA) Serum test, and a Testosterone, Free Direct with Testosterone Total test. Together, these panels give you a look at your testosterone levels, blood cell counts, and PSA marker, which can support monitoring during testosterone replacement therapy. This panel does not diagnose any condition on its own.
2. Who would benefit from this test?
This panel may be useful for men who are currently on testosterone replacement therapy or who are considering it. It may also benefit those who want to keep track of testosterone, blood cell, and PSA markers as part of ongoing monitoring, in coordination with their healthcare provider.
3. When should I order this panel?
You may consider ordering this panel when starting testosterone replacement therapy, or as part of ongoing monitoring while on therapy. It can also be used for periodic follow-up in coordination with your healthcare provider. This panel does not diagnose any condition.
4. Do I need to fast before this test?
No fasting is required. You should stop biotin consumption at least 72 hours prior to collection.
5. How quickly will I get results?
Results are typically available in 7 to 10 days. Results may take longer based on weather, holiday, or lab delays.
6. How do I interpret the results?
Patterns across your testosterone, blood cell, and PSA markers are often more meaningful than any single value viewed alone. Your healthcare provider is best positioned to help you understand what your results mean in the context of your health history and any symptoms you may be experiencing.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
7. What should I do if my results are abnormal?
If any of your results fall outside the expected range, share them with your healthcare provider. They can help you understand what the results may mean and whether any next steps, such as additional testing or adjustments to your therapy, are appropriate.
8. How often should I get tested?
Testing frequency varies from person to person. Follow the schedule recommended by your healthcare provider, especially while starting or adjusting testosterone replacement therapy.
9. Why early detection matters
Regularly monitoring your testosterone, blood cell, and PSA markers may help support earlier awareness of changes during testosterone replacement therapy. This can help you and your healthcare provider stay informed as you manage your therapy over time.
Pre-test preparation
No fasting is required. Avoid ejaculation and strenuous exercise for 72 hours before testing. The patient should stop biotin consumption at least 72 hours prior to the collection. PSA sampling should not be performed for at least six weeks after prostatic biopsy.
