ALBUMIN, FLUID

General Information

Performed: 24 hrs.

Turn Around Time: Med Emerg: 45 minutes; Routine: 2hrs.

CPT Codes: 82042

Performed By: Chemistry

Notes: This is a Laboratory Developed Test.

Clinical Utility: Measurement of certain biochemical parameters are used to determine whether the fluid effusion is a transudate or an exudate. The presence of transudate implies the presence of hydrostatic or colloid pressure disturbance without pleural disease involvement. In contrast, exudate implies infection or a neoplasm causing increased capillary permeability. Albumin: Variable levels suggestive of transudate and exudates are observed with respect to serum levels. The test results should be integrated into the clinical context interpretation.
