Quantitative Ultrafiltration/Quantitative Enzymatic
Plasma separator tube, serum separator tube, or plain red.
Allow specimen to clot completely at room temperature. Separate serum or plasma from cells ASAP or within 2 hours of collection. Transfer 2 mL serum or plasma to an ARUP Standard Transport Tube. (Min: 1.1 mL)
Specimens containing calcium chelating anticoagulants such as citrates, EDTA, or oxalates.
After separation from cells: Ambient: 1 week; Refrigerated: 1 month; Frozen: 1 month
|Amylase, Percent Monomeric||Greater than or equal to 71 percent|
An amylase, monomeric result above the upper reference limit is consistent with hyperamylasemia. An amylase, percent monomeric less than 71 percent suggests the presence of macroamylase.
Amylase, monomeric is determined after ultrafiltration. Macroamylase is removed by ultrafiltration and is not measured.
For confirmation of macroamylasemia, consider ordering Amylase, Urine (ARUP test code 0020471).
Compliance Statement B: For laboratory developed tests not using a RUO kit, and for FDA approved, cleared or 510(k) exempt assays with alterations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.
