Flu is short for influenza. It is a respiratory infection caused by viruses . Respiratory infections may affect your nose, throat, and/or lungs. Most flu tests check a sample of fluid from your nose or throat to find out if you're infected with a flu virus.
Glossary Term
Fluorescence is a luminescence (i.e., optical phenomenon) in cold bodies, in which a molecule absorbs a high-energy photon, and re-emits it as a lower-energy (longer-wavelength) photon. The energy difference between the absorbed and emitted photons ends up as molecular vibrations (heat).
Glossary Term
A class of dyes when excited by light of certain wavelengths, emit photons and become fluorescent. Fluorescence gives fluorochromes imaging characteristics and are used to label or stain biological structures.
Tests
This test measures the level of follicle-stimulating hormone (FSH) in a sample of your blood. A hormone is a chemical messenger in your bloodstream that controls the actions of certain cells or organs. FSH plays an important role in sexual development in children and fertility in adults.
Glossary Term
Refers to a process where a sample is preserved with formalin and then embedded into a paraffin block for sectioning.
Indicators
This gene plays a role in the modulation of gene expression.
Indicators
This gene is involved in transcriptional regulation and may play a role in myogenic growth and differentiation.
Glossary Term
A mutation occurring within the protein-coding region of a gene which results in a shift in the reading frame of the encoded protein. Frameshift mutations often result in the premature truncation of a gene product.
Tests
A free light chains test measures the level of free light chains in your blood. Light chains are proteins made by plasma cells, a type of white blood cell. Light chains usually link up with other proteins called heavy chains. Together, the light and heavy chains make immunoglobulins, also called antibodies. Antibodies are proteins that your immune system makes to fight germs such as viruses and bacteria .
Glossary Term
Tissue that is not frozen or embedded in preservatives
Glossary Term
A tissue sample that has been frozen prior to analysis.
Tests
A fungal culture test helps diagnose fungal infections . Fungal infections may happen if you are exposed to fungi (more than one fungus). Fungi are plant-like life forms, such as yeasts and molds . Fungi live everywhere:
