collection instructions
Collect blood in a serum separator tube (SST) or a lithium heparin tube.
Allow the blood to clot at room temperature for 30 minutes if using an SST.
Centrifuge and separate serum or plasma from cells within 2 hours of collection.
Collect urine over a 24-hour period in appropriate container.
Transport the specimen at 2-8°C if not tested within 2 hours.
collection instructions
Hemolysis: Red blood cell destruction can affect test results.
Clotted Specimen: Plasma specimens must be anticoagulated.
Improper Labeling: Specimen must be labeled with at least two patient identifiers.
Insufficient Quantity: Volume less than 1 mL may not be sufficient for all tests.
Delayed Transportation: Specimens must be processed and tested within the specified time frame to ensure accuracy.
Serum or plasma must be separated from cells within 2 hours and kept refrigerated if there is any delay in testing.
Lipemia: Excessive fat in the blood can interfere with certain test results
clinical significance
The Chloride test measures the concentration of chloride ions in the blood, which is essential for maintaining electrolyte balance, osmotic pressure, and acid-base balance. Abnormal chloride levels can indicate conditions such as dehydration, kidney disorders, acidosis, alkalosis, or diseases affecting the adrenal glands.
