Alkaline Phosphatase, Serum or Plasma
Also known as: ALKP
Use
This test aids in the investigation of hepatobiliary and bone diseases. Abnormal levels of alkaline phosphatase can indicate issues with the liver, gallbladder, or bones, helping healthcare providers diagnose conditions such as liver disease, bone disorders, and bile duct obstructions.
Special Instructions
Collection requires a plasma separator tube or serum separator tube. After collection, separate serum or plasma from cells within 2 hours. Transfer 1 mL to an ARUP Standard Transport Tube. Maintain specimen stability by refrigerating for up to one week or freezing for up to two months. Avoid using specimens collected in EDTA or sodium fluoride/potassium oxalate tubes or those that are grossly hemolyzed.
Limitations
This test may not provide accurate readings if the specimen is collected in EDTA or sodium fluoride/potassium oxalate tubes. Grossly hemolyzed samples can also lead to inaccurate results. Results can vary based on instrumentation, so comparisons should be made with the same equipment type. Ensure proper collection and preparation to maintain sample integrity.
