Your Bloodwork Panel Is Incomplete: The Markers Most Clinics Miss

You get your blood drawn. A week later, your clinic calls with results: "Your testosterone is 450. You are normal. See you next year."

This is the current state of hormone testing for most men. A single number is used to make profound health decisions. The reality is that total testosterone is only one small piece of the puzzle. Without looking at free testosterone, SHBG, estradiol, thyroid function, lipids, hematocrit, and a dozen other markers, you have almost no useful information about your hormonal status.

This article outlines the essential bloodwork markers for anyone tracking their hormones, explains why each one matters, and shows you what healthy ranges actually look like.

The Big Picture Markers

1. Total Testosterone (TT)

Normal range: 300–1,000 ng/dL

This is what most clinics measure. It includes all circulating testosterone: bound and free. While useful as a starting point, total testosterone alone tells you almost nothing about bioavailability or how you will actually feel.

2. Free Testosterone (FT)

Normal range: 8–30 pg/mL (direct measurement)

This is the testosterone that actually binds to androgen receptors and produces effects. It represents only 1–3% of total testosterone, but it is what matters clinically. Men with identical total testosterone levels can have wildly different free testosterone depending on their SHBG.

3. Sex Hormone Binding Globulin (SHBG)

Normal range: 24–122 nmol/L

SHBG binds approximately 97% of your circulating testosterone, making it unavailable to your cells. High SHBG means less free testosterone despite normal or even elevated total testosterone.

SHBG is elevated by estradiol, liver disease, and hyperthyroidism. It is suppressed by insulin, DHT, and visceral adiposity. This is why insulin-resistant men with high visceral fat often have high total testosterone but low free testosterone and symptoms of hypogonadism.

4. Estradiol (E2)

Normal range: 15–60 pg/mL

Estradiol is the primary form of estrogen in men. It is not "bad"—healthy estradiol is essential for bone health, erectile function, and cardiovascular health. But too high or too low creates problems.

High estradiol causes water retention, gynecomastia, and mood disturbance. Low estradiol causes joint pain, erectile dysfunction, and poor recovery. The optimal range is typically 20–50 pg/mL, not the dangerously low ranges that some men crash to with excessive AI use.

5. Bioavailable Testosterone

Calculation: Total T – SHBG-bound T

Some labs calculate this, others do not. It represents the free testosterone plus albumin-bound testosterone (which has some bioavailability). More useful than total testosterone alone, but inferior to direct free testosterone measurement.

Metabolic and Health Markers

6. Hematocrit (HCT)

Normal range: 41–50% (male)

Testosterone increases red blood cell production. Hematocrit is one of the most common markers affected by TRT. Values above 54% create increased blood viscosity and clotting risk. Regular monitoring is essential, and therapeutic phlebotomy may be needed if hematocrit climbs too high.

7. Hemoglobin

Normal range: 13.5–17.5 g/dL

Follows hematocrit. Elevated hemoglobin indicates polycythemia, which requires intervention (dose reduction or phlebotomy).

8. Lipid Panel (Total Cholesterol, LDL, HDL, Triglycerides)

Testosterone therapy often increases triglycerides and lowers HDL—the "bad" lipid changes. Regular lipid monitoring is essential. Dietary optimization and dose adjustment can usually bring lipids back into range.

9. Liver Function Tests (ALT, AST, Albumin)

Injectable testosterone does not cause hepatotoxicity, but baseline and periodic monitoring ensures no other liver disease is developing.

10. Kidney Function (Creatinine, BUN)

TRT does not typically affect renal function, but baseline testing and periodic checks are standard care.

Hormonal Markers

11. Thyroid Panel (TSH, Free T3, Free T4)

Thyroid function affects how you feel as much as testosterone. Men with hypogonadism often have coexisting hypothyroidism. TSH alone is insufficient—free T3 and free T4 provide better insight into thyroid status.

12. Prolactin

Normal range: 4–15 ng/mL

Elevated prolactin suppresses gonadotropins and can reduce testosterone even in men on exogenous therapy. It can indicate pituitary pathology and warrants investigation if elevated.

13. Luteinizing Hormone (LH)

Normal range: 1–8 IU/L

LH is suppressed to near-zero on TRT, which is expected. Baseline LH tells you about your pituitary function and natural production capacity. Post-TRT, LH recovery indicates testicular resilience.

14. Follicle Stimulating Hormone (FSH)

Like LH, FSH is suppressed on TRT. Useful for assessing baseline fertility and recovery potential post-therapy.

15. PSA (Prostate Specific Antigen)

Normal range: < 4 ng/mL (typically)

Baseline PSA before starting TRT is essential. Regular monitoring during therapy detects prostate changes. The claim that TRT causes prostate cancer is myth, but monitoring is still important.

The Complete Panel You Should Get

Before starting TRT:

• Total testosterone, free testosterone, SHBG
• Estradiol
• Complete metabolic panel (liver, kidney, lipids)
• Complete blood count (hemoglobin, hematocrit)
• TSH, free T4
• Prolactin
• LH, FSH
• PSA

Every 3 months for the first year, then every 6–12 months:

• Total testosterone, free testosterone
• Estradiol
• Hematocrit
• Lipid panel
• Liver and kidney function
• PSA (annual)

This is what proper hormone management looks like. It requires more testing, more attention, and more engagement with your healthcare provider. But the result is precision medicine tailored to your individual biology, not guesswork based on a single number.
