Use
This test is used for the measurement of histamine in plasma.
Special Instructions
Not provided.
Limitations
The test was developed and its performance characteristics were determined by Labcorp and have not been cleared or approved by the FDA. Plasma histamine levels may indicate exposure to histamine or other stimuli, but they are less specific for mast cell activation compared to serum tryptase levels. Elevated histamine may occur due to dietary intake, food processing issues, or substance interactions affecting amine oxidase activity.
