Lymphocyte Proliferation to Cobalt
Test Code
COLPT
Description
Cobalt lymphocyte proliferation testing is a clinically relevant tool for the diagnosis of allergic contact dermatitis or cobalt sensitivity. It can be used in situations where patch testing is not recommended. Breathing cobalt particles can cause breathing difficulty and lead to damage to the nose, throat and lungs over time.
Collect
Preferred volume: 30 mL blood. Collect blood in three 10 mL Green (Sodium Heparin) top tubes. Gently invert several times to mix and prevent clots.
