Currently, the examination only screens for pregnancy and infectious diseases such as syphilis, HIV and tuberculosis. Among the new measures is the recording of the maid's weight and height to calculate her body-mass index (BMI). "Over time, this will enable doctors to compare against the migrant domestic worker's past six-monthly examination records, and pick up signs such as significant weight loss for further investigation," said MOM. Doctors will also check for signs of "suspicious and unexplained injuries". "This is complemented by MOM’s and the Ministry of Health's (MOH) guidelines to doctors on what to look out for, and the follow-up actions to take if worrying signs are detected."
