G-I Test Listing

Test Code: 501

CPT Code(s): 86704

Methodology: Immunoassay (IA)

Clinical Significance: This assay does not distinguish between Total B core antibody IgG and IgM detected before or at the onset of symptoms; however, such reactivity can persist for years after illness, and may even outlast anti-HBs. Occasionally Hepatitis B core antibody may be the only marker of either current or past Hepatitis B infection.

Alternative Name(s): Anti-HBC; B Core; Core Ab; Corzyme; Hep B Core Ab

Test Code: 499

CPT Code(s): 86706

Methodology: Immunoassay (IA)

Clinical Significance: The detection of anti-HBs is indicative of a prior immunologic exposure to the antigen or vaccine. To determine immune status as ≥10 mIU/mL as per CDC guidelines, please order Hepatitis B Surface Antibody, Quantitative.

Alternative Name(s): Anti-HBS; Anti-HBS Qual; Anti-HBSAG; Australian Antibody; HB Surface Ab

Test Code: 498

CPT Code(s): 87340

Methodology: Immunoassay (IA)

Includes: Positive samples will be confirmed based on the manufacturer's FDA approved recommendations at an additional charge (CPT code(s): 87341).

Test Code: 482

CPT Code(s): 82977

Methodology: Spectrophotometry (SP)

Test Code: 484

CPT Code(s): 82947

Methodology: Spectrophotometry (SP)

Clinical Significance:Plasma glucose levels may be abnormally high (hyperglycemia) or abnormally low (hypoglycemia). Glucose measurements are used in the diagnosis and treatment of carbohydrate metabolic disorders including diabetes mellitus, idiopathic hypoglycemia, and pancreatic islet cell neoplasm.

Test Code: 10256

CPT Code(s): 80076

Includes: Total Protein, Albumin, Globulin (calculated), Albumin/Globulin Ratio (calculated), Total Bilirubin, Direct Bilirubin, Indirect Bilirubin (calculated), Alkaline Phosphatase, AST, ALT

Methodology: See individual tests

Clinical Significance: See individual tests

Alternative Name(s): Basic liver profile; LFT; Liver Function Profile

Test Code: 483

CPT Code(s): 82947

Methodology: Spectrophotometry (SP)

Limitations: Glucose levels may be depressed if sample is left to clot and not spun for an excessive length of time.

Test Code: 8477

CPT Code(s): 82950

Methodology: Spectrophotometry (SP)

Clinical Significance: A value of 135 mg/dL or greater indicates the need for a full diagnostic, gestational glucose tolerance performed in the fasting state to determine if the patient has gestational diabetes.

Test Code: 8396

CPT Code(s): 84702

Methodology: Immunoassay (IA)

Limitations: Heterophilic antibodies may produce low false-positive results; urinary hCG is negative if "phantom" hCG is suspected. Pituitary secretion may be a source of low level hCG in post menopausal women

Test Code: 91932

CPT Code(s): 87624

Includes: HPV Mrna e6/e7, Rectal

Methodology: Transcription-Mediated Amplification (TMA)

Clinical Significance: The HPV mRNA E6/E7 test is used in conjunction with cytology to evaluate anal dysplasia.

Alternative Name(s): Human Papillomavirus
