Potassium, Misc Fluid

Test Summary

Potassium measurements are useful in monitoring electrolyte balance in the diagnosis and treatment of disease conditions characterized by low or high blood potassium levels. Potassium is elevated in adrenal cortical insufficiency, acute renal failure and in some cases of diabetic acidosis. Potassium is decreased in diuretic administration and renal tubular acidosis.

Aliases

  • Fluid Potassium, Pleural fluid Potassium

Specimen Collection

Special Instructions

List specific body site/type of fluid being submitted.

Preferred Specimen

20 mL abdominal fluid (ascites, peritoneal, paracentesis and pleural fluids ONLY), type identified, free from hemolysis, particulate matter and mucous received in a sterile container.

Minimum Volume

1 mL

Instructions

The type/site of fluid submitted must be noted on the specimen and order. Fluid should be free of mucous, particulate matter, and be non-viscous. All of those factors can affect analysis and may render the fluid non-viable for testing

Patient Preparation

N/A

Storage

Screw-cap container/tube

Transport Temperature

Refrigerated

Specimen Stability

  • Room Temperature = 14 days
  • Refrigerated = 14 days
  • Frozen = N/A

Limitations

Testing can only be perform on approved abdominal fluids. No reference ranges have been established.

Other Acceptable Specimens

N/A

Unacceptable Specimens

Synovial fluids or any fluid that is not considered an abdominal fluid. Also fluids received in tubes with preservatives. Criteria is variable depending on the specific type of fluid sample received. In general, gross hemolysis, elevated viscosity, and particulate matter may cause interferences with analytical methods.
