anti-HBc/EIA

HBsAg/EIA

HBsAg/EIA refers to a version of the tests used specifically by the Laboratoire de santé publique du Québec (LSPQ) to confirm all non-negative HBsAg (Hepatitis B surface antigen) results produced in Quebec by both hospital and private laboratories. Hepatitis B is a reportable disease.

Non-reactive HBsAg/EIA and anti-HBc/EIA: viral infection not detected.

Reactive HBsAg/EIA and anti-HBc/EIA: confirmed infection by the hepatitis B virus.

The other combinations of results are followed by automatic confirmation tests and specific indications for the process to be followed: confirmed positive or negative result, invitation to re-test on a new sample.

Hot zone

A hot zone is a section of a facility (sometimes an entire facility or even a city district) where there is a high risk of contamination by patients with an infectious disease. All individuals entering a hot zone must respect appropriate protective measures. By analogy, “cold zone” and “warm zone” are used to refer to areas where there is no infected individual or only individuals suspected of having an infection.
