What is the CT threshold for PCR tests in Thailand regarding recently recovered individuals?
Technical question. Rumor has it that Thailand has a lower threshold for PCR tests that might catch people recently recovered
I’d like to put fact to this rumor. Does anyone know what CT threshold they use?

Answer summary
The conversation revolves around the CT threshold used in PCR tests in Thailand, particularly in relation to individuals who have recently recovered from COVID-19. Participants mention varying CT values from different testing experiences, with some reporting thresholds of 40 or 26. There is a concern about whether Thailand's testing policies might catch recently recovered individuals, with suggestions of blood antibody tests as an alternative for those with recovery certificates.
