Preferred Specimen

FLUID (FLD)

Instructions

Body Fluids: Freshly drawn Body fluids in Red Top or lithium heparinized tubes are recommended. Separate from cells as soon as possible to minimize loss of glucose through glycolysis.

Specimen Stability

Glucose in Body fluids, separated from any cells, free bacterial contamination, and without added preservatives, is stable for 8 hours when stored at room temperature (15-25°C), or 72 hours when stored refrigerated at 2-8°C.

Reference Range

Synovial Fluid	70-99 mg/dL
Peritoneal (Ascites), and Pleural effusions helps differentiate Transudates or Exudates.The following is generally true for their glucose levels:	Transudate: 70 - 99 mg/dL Exudate: < 70 mg/dL

Clinical Significance

Synovial Fluids: Comparing synovial fluid glucose to plasma glucose can be helpful in classifying joint effusions.
Body Fluids: Glucose and other analytes such as LDH, total protein, and cholesterol from other Body fluids, such as peritoneal (ascites), Pleural can be used to help differentiate whether the fluid is a transudate or an exudate.*
*Effusion of serous fluid can be placed into two general categories: transudates and exudates.
A transudate is created by an imbalance of pressure within the blood vessels and the amount of protein in the blood. An example is the changes in hydrostatic pressure created by congestive heart failure.
Exudates are produced by conditions that directly involve the membranes of the particular cavity including infections, injury, and malignancies. Analysis of body fluid usually includes one or more of the following: cell count, differential, total protein, crystals, pH, specific gravity, glucose, albumin, amylase, sodium, potassium, chloride, LDH, creatinine, urea nitrogen, uric acid, routine culture, and cytologic studies.
