Histamine, Whole Blood
Also known as: HIST-WB
Use
This test aids in the evaluation of patients with allergic signs and symptoms such as anaphylaxis and may assist in diagnosing and monitoring mast-cell activation disorders. It provides quantitative measurement of histamine levels in whole blood, which can be critical for assessing hypersensitivity and allergic reactions.
Special Instructions
Ensure the blood sample is collected in a green (sodium or lithium heparin) tube. After collection, transfer 1 mL of well-mixed whole blood to an ARUP Standard Transport Tube and freeze. Submit separate specimens when multiple tests are ordered.
Limitations
The test was developed and its performance characteristics were determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration but is performed in a CLIA certified laboratory intended for clinical purposes. It may not be suitable for all testing scenarios and therefore should be used with caution in clinical assessment.
