Mast Cell Tryptase
Investigation : Mast Cell Tryptase
Spec container : Plain tube 
Volume required : 5ml
Reference range : 2 - 14 g/L
Turnaround : <7 days
Notes: When investigating patients with suspected anaphylaxis, paired samples (the first taken as soon as possible after the onset of symptoms, the second at least 6 hours later) can be useful in confirming that mast cell activation has occurred. A persistently elevated mast cell tryptase suggests the possibility of systemic mastocytosis.
