In the most basic sense, there are four possible outcomes for a COVID-19 test, whether it’s molecular PCR or rapid antigen: true positive, true negative, false positive, and false negative.
COVID-19 Antigen Rapid Test Kit; the timer is provided by the user. Mucus from nose or throat in a test liquid is placed onto a COVID-19 rapid antigen diagnostic test device. COVID-19 rapid testing in Rwanda. An antigen is the part of a pathogen that elicits an immune response. Antigen tests look for antigen proteins from the viral surface.
But if you test negative with an at-home test, the answer will depend in part "on whether the negative COVID test is at the beginning of feeling sick or on the way to recovery,” Mina says.
Cellular immunity, also known as cell-mediated immunity, is an immune response that does not rely on the production of antibodies. Rather, cell-mediated immunity is the activation of phagocytes , antigen-specific cytotoxic T-lymphocytes , and the release of various cytokines in response to an antigen .
If you test negative using an at-home test, repeat the test again in 48 hours. If you were exposed to COVID, test at least 5 full days after exposure. If you still test negative, wait 48 more ...
Humoral immunity is also referred to as antibody-mediated immunity. The study of the molecular and cellular components that form the immune system , including their function and interaction, is the central science of immunology .
Antibody-dependent cellular cytotoxicity (ADCC), also referred to as antibody-dependent cell-mediated cytotoxicity, is a mechanism of cell-mediated immune defense whereby an effector cell of the immune system kills a target cell, whose membrane-surface antigens have been bound by specific antibodies.

On 1 May, Quotient Limited announced the CE Mark for its MosaiQ COVID-19 antibody test, [82] designed as a serological disease screen specific to the Coronavirus. [83] The test has a 100% sensitivity and 99,8% specificity claim. [84] [85] On 3 May, Roche received an EUA for a selective ELISA serology test. [86] [87]
