On Demand Medical Testing

Magnesium measurements are used in the diagnosis and treatment of hypomagnesemia (abnormally low plasma levels of magnesium) and hypermagnesemia (abnormally high plasma levels of magnesium). Magnesium is decreased in chronic nephritis, acute pancreatitis, and alcoholic cirrhosis. It is increased in acute or chronic renal failure and Addison's Disease.

Magnesium is an essential trace element. Deficiency leads to irritability, neuromuscular abnormalities, cardiac and renal damage. Its salts are used as antacids and cathartics. Excessive amount may cause CNS depression, loss of muscle tone, respiratory and cardiac arrest.

Measles is an acute infection caused by Rubeola Virus.

Mononucleosis tests are blood tests to look for antibodies that indicate mononucleosis (mono), which is caused by the Epstein-Barr virus (EBV). The antibodies are made by the immune system to fight an infection

Mumps is an acute, usually self-limited systemic illness characterized by parotitis, high fever and fatigue. One-third of infections are asymptomatic. A live attenuated vaccine is available. The mumps IgG antibody test is sufficiently sensitive to establish immune status of the patient.

NSE is useful in monitoring disease progression and therapy in patients with small cell lung cancer and neuroendocrine tumors such as neuroblastoma, medullary thyroid carcinoma, and pheochromocytoma, and other malignancies such as pancreatic islet cell carcinoma

Prealbumin is decreased in protein-calorie malnutrition, liver disease, and acute inflammation. It may be used as an indicator of nutritional requirements and response to therapy during total parenteral nutrition and as a biochemical marker of nutritional adequacy in premature infants.

A progesterone test measures the amount of the hormone progesterone in a blood sample.

Screening test for abnormalities of coagulation factors that are involved in the extrinsic pathway. Also used to monitor effects of Warfarin therapy and to study patients with hereditary and acquired clotting disorders.

A prostate-specific antigen (PSA) test measures the amount of prostate-specific antigen in the blood.
