All NiaHealth tests are processed in Canadian-certified labs, which are highly trusted by the medical community for their accuracy and reliability. Blood and urine samples are collected by licensed medical professionals and processed using state-of-the-art equipment. NiaHealth is SOC2 Type 2 certified.

This metric compares the levels of beneficial bacteria and the levels of potentially harmful antibiotic-resistant bacteria. Higher numbers mean that you have more antibiotic-resistant bacteria, which might happen after you have had an illness or had to take some antibiotics. You can improve your results by encouraging the growth of beneficial bacteria.
