Know Your Numbers: The 9-Marker Blood Panel for Men Who Train

What's inside

What you'll be able to read for yourself

• The full 9-marker panel: total testosterone, free testosterone, SHBG, fasting glucose, HbA1c, lipid panel, hs-CRP, vitamin D and ferritin, with what each one measures and how it ties to your energy and recovery.
• The optimal-for-training ranges that sit inside the normal band, so you understand why a result the lab flags as green can still leave you feeling flat.
• How to read ferritin when you train hard: the causes worth checking when it runs low, why inflammation or a hard session can make low stores look normal, and the level below which stores are depleted.
• Vitamin D and hs-CRP explained: why Bangkok living leaves many men low on vitamin D, what quietly raised inflammation does to energy and recovery, and the thresholds that matter.
• A one-page test-prep checklist: a fasted morning draw, no maximal workout in the 24 hours before (heavy training kept 48 to 72 hours away if hs-CRP is on the panel), and the two-sample rule before any low-testosterone diagnosis.
• What to do with your results: which numbers to leave alone, recheck or act on, when a retest is worth it, and what a recheck or a wider work-up costs in Bangkok in 2026.
