Nowadays, you will find two types of tests for Coronavirus, which provide different types of information. Diagnostic tests tell us if someone is currently infected and antibody tests tell us if an individual was infected in the past and has an immune response. Antibodies are formed by the body to fight off infections. IgM is the earliest antibody that is formed against a germ, so it appears on tests first, usually within 1-2 weeks. The body then forms IgG, which appears on tests about 2 weeks as soon as the illness starts. IgM usually disappears. At Medical PPE Resource, we provide several kinds of kits to detect either IgG or IgM or both at the same time. A qualitative kit is rapidly detect human IgM and IgG antibodies against COVID-19/ SARS-CoV-2 virus in human whole blood, serum and plasma samples. All of these kits are used by healthcare professionals. For more info, visit
