Lactate Dehydrogenase (LD)

Test Code: 593

CPT Code(s): 83615

Methodology: Spectrophotometry (SP)

Clinical Significance: Elevations in serum lactate dehydrogenase occur from myocardial infarction, liver disease, pernicious and megaloblastic anemia, pulmonary emboli, malignancies, and muscular dystrophy. Since lactic dehydrogenase is present in many body tissues, it's diagnosis usefulness is limited. Tissue specificity may be enhanced by isoenzyme analysis.

Cystic Fibrosis Screen

Test Code: 10458

CPT Code: 81220

Alternative Name(s): CF Mutation Screen, Cystic Fibrosis Mutation Screen, CFTR Screen, CF Carrier Screen, CF Screen, Cystic Fibrosis Carrier Screen

Methodology: Multiplex Polymerase Chain Reaction • Massively Parallel Sequencing

Urinalysis, Complete, with Reflex to Culture

Test Code: 3020

CPT Code(s): 81001

Clinical Significance: Dipstick urinalysis is important in accessing the chemical constituents in the urine and the relationship to various disease states. Microscopic examination helps to detect the presence of abnormal urine cells and formed elements. Culture may identify the organism(s) causing infection.

Includes: Macroscopic and Microscopic Examinations - A culture is performed, when appropriate, at an additional charge (CPT code(s): 87088, 87086).

Culture, Salmonella / Shigella / Campylobacter and Shiga Toxin Reflex E. Coli O157

Test Code: 32114

Includes:
  • Salmonella and Shigella, Culture
  • Campylobacter, Culture
  • Shiga Toxins, EIA with Reflex to E. coli O157, Culture

If Shiga Toxin, EIA is Detected, Escherichia coli O157, Culture will be performed at an additional charge.

If culture is "Isolated", identification will be performed at an additional charge.
Antibiotic susceptibilities are only performed when appropriate.
