Yes it is 3 months in all countries and if you will google it you will find the CDC in India.
No not for all country, but I can tell you that here in India govt follows the US criteria for evaluating window period , So this is 3 months for US and India as far I knw. Hope this is same for Srilanka also.

CDC is for America, You have labs and hospitals accredited by your govt and by others international standard in your country. So as long as you had tested from any reputed laboratories of your country there is no need to think about the reliability.
