ICD-10 Reference
STD codes & confirmation tests
The WHO ICD-10 code for each infection, the test that confirms your status after treatment, whether it can be cured, and whether antibodies stay in the blood for life.
Medical disclaimer: General reference only — not a diagnosis. Your doctor decides which tests you need and when. On NoSTDs, these codes stay private: they are never shown to partners or anyone you share with.
