GLUCOSE, FLUID

General Information

Performed: 24 hrs.

Turn Around Time: Med Emerg: 60 minutes; Routine: 4 hrs.

CPT Codes: 82945

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. The following is indicative of exudate effusion: Glucose lower than serum value. The test result should be integrated into the clinical context interpretation.
