Tests
Legionella is a type of bacteria . When it affects your lungs, it can cause a severe form of pneumonia known as Legionnaires' disease . Legionella tests look for these bacteria in urine, sputum, or in some cases in lung tissue. A blood test may be done to check if you have been exposed to the bacteria, but it cannot diagnose a Legionella infection.
Tests
An assay that measures the proliferative response of lymphocytes from one individual when they are exposed to inactivated lymphocytes from another individual. The reaction can be performed on lymphocytes from the same individual (auto-MLR), from different individuals of the same species (allo-MLR), or individuals from different species (xeno-MLR). It is used to evaluate the potential for graft-versus-host or host-versus-graft reactions during transplantation procedures involving mismatched tissue types or individuals.
Tests
A MRSA test looks for MRSA bacteria in a sample of fluid or tissue from your body. The sample is often taken from your nose or a wound. MRSA stands for methicillin-resistant Staphylococcus aureus . It is a type of staph bacteria.
Tests
Myasthenia gravis (MG) tests are used to diagnose MG, a chronic (long-lasting) autoimmune disease that causes weakness in muscles throughout your body. In autoimmune diseases, your immune system mistakenly attacks the healthy cells of your organs and tissues. If you have MG, your immune system makes antibodies that block or change the connection between your nerves and muscles.
Tests
A measurement of the peak myoglobin normalized for tissue water volume, in a sample.
Tests
A measurement of the peak myoglobin normalized for tissue weight, in a sample.
Tests
PCR (polymerase chain reaction) tests are a reliable and accurate way to diagnose certain infectious diseases , some types of cancer , and certain genetic changes. The tests check for small amounts of genetic material of a pathogen (disease-causing organism) or abnormal cells in a sample of your blood, saliva, mucus, or tissue. The genetic material could be:
Tests
A PD-L1 test uses a sample of cancerous tumor tissue to measure how much of a protein called programmed-death ligand 1 (PD-L1) is found on the cancer cells. Normally, PD-L1 is found on certain healthy cells. It helps keep your immune system from attacking healthy tissue by acting as a kind of "brake" on your immune system cells (called T-cells). However, in some cancers, PD-L1 keeps your immune system from attacking cancerous cells.
Tests
Platelets, also known as thrombocytes, are small blood cells. They form in your bone marrow, the sponge-like tissue in your bones. Platelets are essential for blood clotting . A blood clot is a mass of blood that forms when platelets, proteins, and cells in the blood stick together. When you get hurt, your body forms a blood clot to stop the bleeding.
Tests
The number of proliferating cells found during a review of a slide(s) derived from a tissue sample.
Tests
A protein produced by prostate tissue; elevated values can reflect prostate cancer but also common benign conditions.
Tests
A PTEN genetic test uses a sample of your blood or other body tissue to look for changes in a gene called PTEN . Changes in your genes are also called gene variants or mutations.
