Tests
An ANA test is a blood test that looks for antinuclear antibodies in your blood. Antibodies are proteins that your immune system makes to fight foreign substances, like viruses and bacteria. But an antinuclear antibody attacks your healthy cells instead. It's called "antinuclear" because it targets the nucleus of the cells, which is in charge of sending signals that are needed for important cell functions.
Tests
Blood proteins released when heart muscle is injured; the primary laboratory marker in the evaluation of possible acute myocardial infarction.
Glossary Term
A DNA sequencing technique in which a mixture of deoxynucleosidetriphosphates (dNTPs) and chain-terminating dNTPs, which are radioactively or fluorescently labeled, are combined within the reaction mixture. Once the reaction is complete, the DNA strands are separated by size, and the labeled chain terminating dNTPs can be read in sequence by the investigator or by a machine.
Tests
An immunoassay in which a fluorescent-labeled antibody binds directly to a target antigen.

Glossary Term
Amplification of several targets in a single reaction using multiple primer pairs, each distinguishable by fluorescent channel or melting profile. Multiplexing raises information per sample but makes channel allocation, dye compatibility, and competition between targets key selection criteria.
Tests
A biomarker that rises markedly in systemic bacterial infection; used to support antibiotic decisions in respiratory infections and sepsis pathways.
Glossary Term
A PCR method that measures amplification as it happens using fluorescent reporters, so target quantity is estimated from the amplification curve rather than by post-run handling. qPCR is the workhorse format for viral load, pathogen detection, and GMO or food testing workflows.
