M-O Test Listing

Magnesium

Test Code: 622

CPT Code(s): 83735

Methodology: Spectrophotometry (SP)

Clinical Significance: 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.

Alternative Name(s): MAG

Osmolality, Serum

Test Code: 677

CPT Code(s): 83930

Supply: 53712 Red Top Tube (NO GEL) 10mL

Methodology: Freezing Point Depression

Clinical Significance: Serum osomolality is increased in hypernatremia, hyperglycemia, uremia, ethanol, methanol, or ethylene glycol overdoses, and in diabetes insipidus.

Additional names: N/A

Obstetric Panel

Test Code: 20210

CPT Code(s): 80055, 85025, 86592, 86762, 86850, 86900, 86901, 87340

Includes:
CBC (includes Differential and Platelets)

Antibody Screen, RBC with Reflex to Identification, Titer, and Antigen Typing

Myoglobin

Test Code: 58723

CPT Code(s): 83874

Methodology: Chemiluminescent Microparticle Immunoassay (CMIA)

Clinical Significance: Myoglobin is a sensitive indicator of acute myocardial infarction (AMI), but is not specific for cardiac muscle

Alternative Name(s): Myo, MYB

Myoglobin, Urine

Test Code: 661

CPT Code: 83874

Methodology: Fixed rate time nephelometry

Clinical Significance: The breakdown of skeletal muscle (rhabdomyolysis) releases myoglobin. Very high concentrations of myoglobin may increase the risk of acute renal failure.

Alternate Names: N/A

Methicillin Resistant Staphylococcus Aureus Culture Screen

Test Code: 90417

CPT Code: 87081

Methodology: Chrom Aagar method

Reference Range(s): No Methicillin Resistant Staphylococcus aureus (MRSA) isolated.

Clinical Significance: MRSA is a major cause of nosocomial and life-threatening infections. Infections with MRSA have been associated with a significantly high morbidity, mortality and cost. Selection of these organisms has been greatest in the health care setting. However, MRSA has also become more prevalent in the community.
