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).

Specimen

  
Serum
  
  
0.5 mL
  
0.2 mL
  

Immediatley following collection, mix sample by gently inverting 5 times

  
  1. Allow sample to clot for a minimum of 30 minutes
  2. Spin
  

Gold serum separator (SST) tube

  
EDTA plasma
Sodium citrate (Na cit)plasma
Sodium flouride (Na fl) plasma
Heparin plasma
  
  
0.5 mL
  

Red:

  1. Allow sample to clot
  2. Spin
  3. Immediately (30 minutes) transfer serum to a Transfer vial/tube with cap - 12mL (LabCorp) labelled as "serum"

Lavender, Lt blue, Grey or Dk green:

  1. Spin
  2. Immediately (30 minutes) transfer plasma to a Transfer vial/tube with cap - 12mL (LabCorp) labelled as the appropriate type of plasma.

Not removing refrigerated specimens from the clot/cells results in aldolase levels 12% to 46% higher.

  
  

Refrigerated (preferred) - 7 days
Ambient - 1 day
Frozen - 15 days

  
  • Hemolysis (red cells contain aldolase)
