Temperature: Refrigerated
Tube Type: SST, Red-top, Citrate, EDTA, Heparin, Fluoride

Specimen Acceptability

Rejection criteria: Hemolysis

Methods

Kinetic − 340 nm at 37°C

Clinical Utilities

Use:  Evaluate muscle wasting process. High levels are found in progressive Duchenne muscular dystrophy (MD). Elevations occur in carriers of MD, in limb-girdle dystrophy and other dystrophies, in dermatomyositis, polymyositis, and trichinosis, but not in neurogenic atrophies (eg, multiple sclerosis or in myasthenia gravis).

Limitations:  As muscle mass diminishes, aldolase decreases. Serum aldolase elevation is not specific for muscle disease since it is present in many tissues (see Additional Information).
