Glossary Term
A method used to test whether the mean difference between pairs of measurements in a related group are significant.
Tests
A parainfluenza test checks a fluid sample from your nose or lungs for the four types of parainfluenza viruses (also called human parainfluenza viruses, or HPIVs). These viruses are a common cause of respiratory (breathing) illnesses, especially in spring, summer, and fall.
Glossary Term
In statistical inference procedures (hypothesis tests and confidence intervals), parametric procedures are those that incorporate assumptions about population parameters.
Indicators
Parathyroid hormone (115 aa, ~13 kDa) is encoded by the human PTH gene. This protein is involved in the modulation of calcium ion and phosphate concentration in the blood.
Tests
This test measures the level of parathyroid hormone (PTH) in your blood. PTH, is made by your parathyroid glands . They are four pea-sized glands in your neck.
Tests
A partial thromboplastin time (PTT) test uses a blood sample to measure the number of seconds it takes for your blood to clot . Normally, when you get a cut or injury that causes bleeding, many different types of proteins in your blood work together to make a clot to stop the bleeding. These proteins are called coagulation factors or clotting factors, and your liver makes most of them.
Indicators
This gene is involved in the transcriptional regulation of target genes. It plays a role in B-cell differentiation, neural development and spermatogenesis.
Indicators
This gene plays a role in chromatin remodeling.
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:
Indicators
This gene plays a role in mitogenic activities affecting mesenchymal cells and a translocation in the gene results in chronic myelomonocytic leukemia.
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.
Glossary Term
A measure of the correlation of two variables X and Y measured on the same object or organism, that is, a measure of the tendency of the variables to increase or decrease together. It is defined as the sum of the products of the standard scores of the two measures divided by the degrees of freedom.
