Check Your T Without a Doctor's Visit

Fatigue that coffee can't fix. A libido that went quiet. Workouts producing diminishing returns. If this sounds familiar, testosterone might be the culprit — and you can check from home for under $100.

What You Need to Measure

Total Testosterone: Normal range 300–1,000 ng/dL; many clinicians consider "optimal" above 500 ng/dL.

Free Testosterone: Only 2–3% circulates unbound. You can have normal total T but low free T and still feel symptoms.

SHBG: Binds testosterone, making it unavailable. High SHBG means less free T even if total T looks fine.

Estradiol: Elevated in obese men from aromatization. Suppresses T production and causes fatigue, water retention.

Key Takeaway: Total testosterone alone tells an incomplete story. Free T and SHBG are essential for understanding whether your body can use the testosterone it produces.

Saliva vs. Blood

Blood tests are the gold standard — total T, free T, binding proteins measured directly from serum with decades of reference ranges. Use blood for medical decisions.

Saliva tests measure free T only, with less precision. Useful as a $49 screening tool. Low saliva result? Follow up with comprehensive blood panel.

⚠️ Important: Test before 10 AM after fasting overnight. T peaks in the morning and drops 20–30% by afternoon. One low reading isn't a diagnosis — confirm with a second test.

Reading Your Results

Marker	Normal	Optimal	Red Flag
Total T	300–1,000 ng/dL	>500 ng/dL	<300 ng/dL
Free T	5–21 pg/mL	>9 pg/mL	<5 pg/mL
SHBG	10–57 nmol/L	20–40 nmol/L	>60 nmol/L
Estradiol	10–40 pg/mL	20–30 pg/mL	>50 pg/mL
LH	1.8–8.6 mIU/mL	4–6 mIU/mL	<1.5 or >12

If Your T Is Low

Confirmed low T (total <300 ng/dL on two morning tests) warrants action. Many men start with lifestyle changes — weight loss, resistance training, sleep, and stress reduction can raise T by 15–30% in overweight men. For levels that don't respond, TRT is available through telehealth.

Frequently Asked Questions

Is a $49 saliva test worth it?

As a screen, yes. Normal result gives reassurance. Low result means follow up with blood panel before treatment decisions.

How often to test?

Normal and asymptomatic: annually after 35. On TRT: every 3–6 months. Making lifestyle changes: retest after 3 months.

Can supplements raise testosterone?

Marginally, only if deficient. Vitamin D, zinc, magnesium may modestly support T. Nothing OTC takes you from 250 to 600 ng/dL.

Do at-home tests accept insurance?

Most don't. But at $49–199, they're often cheaper than copay + lab fee. HSA/FSA funds usually eligible.
