Which Test for Covid 19?

Swab samples use a swab (similar to a long Q-Tip) to collect a sample from the nose or throat. The types of samples include:

•Anterior Nares (Nasal) – takes a sample from just inside the nostrils
•Mid-turbinate – takes a sample from further up inside the nose
•Nasopharyngeal – takes a sample from deep inside the nose, reaching the back of the throat
•Oropharyngeal – takes a sample from the middle part of the throat (pharynx) just beyond the mouth

Saliva samples are collected by spitting into a tube rather than using a nose or throat swab.

Blood samples are only used to test for antibodies and not to diagnose COVID-19. Venous blood samples are typically collected at a doctor’s office or clinic. Some antibody tests use blood from a finger stick.
