stability at 4 degrees C

• AST specimen stability is 3-4 days at 4 degrees C
• ALT specimens are stable for 3-4 days at 4 degrees C
• acid phosphatase samples Can be stored for 2 days at 4 degrees C, adding acid to sample would increase acid phosphatase activity, but we dont do that
• GGT samples - serum is stable for 1 week at 4 degrees C
• GGT specimens are stable for 1 week at 4 degrees C
