SARS-CoV-2 IgG/IgM Rapid Qualitative Test

The SARS-CoV-2 Antigen Rapid Qualitative Test is a colloidal gold immunochromatography intended for the qualitative detection of nucleocapsid antigens from SARS-CoV-2 in human nasal swabs, throat swabs, and sputum from individuals who are suspected of COVID-19 by their healthcare provider. within the first five days of the onset of symptoms.

Biotime SARS-CoV-2 Antigen rapid test is a fluorescence immunoassay(FIA) for the quantitative detection of SARS-CoV-2 in human nasal swab. It is useful as an aid in monitoring and management of COVID-19 infection.

Biotime SARS-CoV-2 Neutralizing Antibody rapid test is a fluorescence immunoassay(FIA) for the qualitative detection of total neutralizing antibodies to SARS-CoV-2 in human serum or plasma. It is useful as an aid in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection.

β-HCG is a fluorescent immunoassay for the quantitative measurement of β-HCG level in human serum and whole blood. This test is performed to help diagnose pregnancy if a woman is to undergo a medical treatment, be placed on certain drugs, or have other testing, such as x-rays, that might harm the developing baby.

Immunoglobulin E (IgE) is a type of antibody (or immunoglobulin (Ig)"isotype") that has only been found in mammals. IgE is synthesised by plasma cells. IgE's main function is immunity to parasites such as helminths like Schistosoma mansoni, Trichinella spiralis, and Fasciola hepatica. Total IgE is utilized during immune defense against certain protozoan parasites such as Plasmodium falciparum. Total IgE may have evolved as a last line of defense to protect against venoms.

Homocysteine, often shortened to HCY, is a thiol containing amino acid produced by the intracellular demethylation of methionine. Excess HCY in the bloodstream may cause injuries to arterial vessels due to its irritant nature and result in inflammation and plaque formation, which may eventually cause a blockage of blood flow to the heart.

The RSV antigen rapid test is intended to be used by professionals as a screening test and to provide preliminary test results to help diagnose acute RSV virus infection. It provides only an initial screening test result.  For professional in vitro diagnostic use only.

Ferr is a universal intracellular protein that stores iron and releases it in a controlled fashion. The protein is produced by almost all living organisms, including algae, bacteria, higher plants, and animals. In humans, it acts as a buffer against iron deficiency and iron overload. Ferritin is found in most tissues as a cytosolic protein, but small amounts are secreted into the serum functioning as an iron carrier. Plasma ferritin is also an indirect marker of the total amount of iron stored in the body. Hence serum ferritin is used as a diagnostic test for iron-deficiency anemia.
