MLTBARCODE (HML34) is a 5-digit bar code for the household member's blood smear sample. A blood smear is collected on a microscope slide, and the slide is labeled with a bar code instead of the person's name to protect confidentiality.
Microscopy analysis of the blood on the slide in a central laboratory can detect the presence of parasites in the blood as an indicator of malaria at the time of the survey.
