Tests
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.
Indicators
A collective term for pteroylglutamic acids and their oligoglutamic acid conjugates. As a natural water-soluble substance, folic acid is involved in carbon transfer reactions of amino acid metabolism, in addition to purine and pyrimidine synthesis, and is essential for hematopoiesis and red blood cell production. (NCI05)
Indicators
A heterodimeric glycoprotein hormone secreted by the gonadotropic cells of the anterior pituitary gland. This hormone is involved in gonadal development, growth, maturation and reproductive processes, including the regulation of spermatogenesis in males and follicular growth and ovulation in females.
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.
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 .
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:
Tests
This test measures the amount of G6PD in your blood. G6PD stands for glucose-6-phosphate dehydrogenase. It's an enzyme, a protein that speeds up certain chemical reactions in your body. It helps your red blood cells work properly. Red blood cells move oxygen from your lungs to every cell in your body. Your cells need oxygen to grow, reproduce, and stay healthy.
Tests
A galactosemia test is a blood test given to newborns to check for a rare genetic metabolic disorder called galactosemia. Metabolic disorders affect metabolism, the process your body uses to make energy from the food you eat. Galactosemia can be inherited (passed down through families), but to have the condition, your baby has to receive the gene from both parents. Genes are parts of DNA in your cells that you inherit from your parents. You inherit two copies of each gene, one from each parent.
Tests
A gamma-glutamyl transferase (GGT) test measures the amount of GGT in your blood GGT is an enzyme. Enzymes are proteins that speed up certain chemical reactions in your body. Thousands of enzymes play an important role in all of your body functions. The GGT enzyme is found throughout your body, but it is mainly found in your liver.
