103039-4 Chlorhexidine IgE Ab [Presence] in Serum by Radioallergosorbent test (RAST)

Part Description

LP128648-5   Chlorhexidine
Chlorhexidine is a cationic chlorophenyl biguanido antiseptic and disinfectant and is commonly used as the diacetate or digluconate salt. Its structure is symmetrical with two identical epitopes, which implies that chlorhexidine per se would be capable of cross linking IgE antibodies on the surface of mast cells and basophiles thereby eliciting allergic reactions by histamine release in sensitized individuals. This mechanism has been demonstrated with similar divalent drugs such as the muscle relaxant suxamethonium.

Exposure to the allergen often occurs as skin disinfection prior to surgery and blood tests or by urinary catheterization, disinfection of a drain insertion site, or placement of a central venous catheter. Exposure also occurs upon use of gel in vaginal and rectal examinations and in connection with dental procedures. Chlorhexidine exposure is also wide-spread in homes from use of numerous products such as cleaning fluids, toothpastes, mouth rinses etc. Copyright Copyright © 2006 Phadia AB.

Change Reason
Release 2.75: Status: In order to give the data more machine reading and classification power, we deprecated the RAST class components because they are combination of Component/Analyte and Method RAST. We replaced them with new Component/Analyte by removing ".RAST Class", and we added new method "RAST" in the Method axis. Since these tests are falling under Semi-Quantitative project, we changed their previous Scale value to the new Scale value of "SemiQn"; Previous Releases: The Property has been changed from ACnc to Threshold to reflect the new model for ordinal terms where results are based on a cut-off value.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; The Answer list type has been changed from 'Normative' to 'Example' due to the variability of the calibrator and the number of classes. Some labs use a low calibrator of 0.1 KU/L and include an additional 0/1 class, while other labs have continued with the 0.35 KU/L calibrator and have only 7 classes.
