| Typical dose | Not applicable to drug dosing — what matters here is the numerical hematocrit value on a blood count and how it relates to the thresholds: <50% (normal), 50–54% (vigilance), ≥54% (intervention). | Not applicable — this piece describes the full diagnostic pathway preceding TRT, not a drug dosing schedule |
| Form | Complete blood count with hematocrit (Hct) and hemoglobin (Hb) — a standard venous blood draw, ideally done well hydrated and at a similar time of day across follow-ups for comparable results. | Blood tests: total testosterone (2x morning), free testosterone, SHBG, LH, FSH, prolactin, estradiol, complete blood count with hematocrit, PSA, lipid panel, fasting glucose or HbA1c, liver function tests, TSH; plus a digital rectal exam and an ADAM/AMS symptom questionnaire |

| Time to effects | The thresholds described in this entry concern interpreting a result at a given moment, not an effect building up over time — the typical time for hematocrit to stabilize after starting or modifying therapy runs from a few weeks to about 3 months. | Not applicable — a diagnostic pathway preceding any possible start of therapy, usually taking several weeks. |
| Who it's for | Men on TRT who just got a blood count result and want to know where their hematocrit falls on the scale and whether it calls for a response | Men with symptoms suggesting testosterone deficiency (reduced libido, erectile dysfunction, chronic fatigue, loss of muscle mass) considering TRT |
