Amylase, Serum or Plasma
Also known as: AMY
Use
Amylase testing is significant for assessing pancreatic function and diagnosing pancreatic disorders, including acute pancreatitis and chronic pancreatitis. It is also useful for diagnosing certain genetic conditions like cystic fibrosis that affect the pancreas, as well as assessing the cause of abdominal pain and digestive issues.
Special Instructions
Collect specimen within two hours of the procedure and separate serum or plasma from cells promptly to avoid inaccuracies in results. Ensure to avoid using calcium chelating anticoagulants such as oxalates, citrates, or EDTA which can lead to the rejection of the specimen.
Limitations
Amylase levels may be elevated in conditions other than pancreatic disease, such as salivary gland disorders, ectopic pregnancy, and certain cancers. The test may not detect all genetic mutations related to conditions such as cystic fibrosis. Additionally, specimen collection and preparation errors can lead to inaccurate results, emphasizing the importance of adhering to specified procedures.
