Edit Date: | 10/31/2006 | ||||||||
Performed: | Daily | ||||||||
Released: | Same day | ||||||||
CPT Code: | 82638 | ||||||||
Specimen Collection Details | |||||||||
Collection: | One 7.5 mL serum separator tube (SST). Specimen believed to contain succinylcholine (given as anesthesia in surgery) should be placed on ice. | ||||||||
Handling: | Centrifuge immediately and transport in original tube. Keep cold. | ||||||||
Stability: | 14 days refrigerated. | ||||||||
Standard Volume: | 2 mL serum. | ||||||||
Minimum Volume: | 0.5 mL serum. | ||||||||
Transport: | Refrigerated. | ||||||||
Comments: | The prompt handling of the specimen limits the in vitro destruction of the inhibitor. This test measures the activity of pseudocholinesterase in the presence of dibucaine. See also: Pseudocholinesterase (31760). |
