  • Title: Sensitive glass microfibre-based histamine analysis for allergy testing in washed blood cells. Results compared with conventional leukocyte histamine release assay.
    Author: Skov PS, Mosbech H, Norn S, Weeke B.
    Journal: Allergy; 1985 Apr; 40(3):213-8. PubMed ID: 2581468.
    Abstract:
    The new microfibre method for allergy testing is based on basophil histamine release after challenge with suspected allergens in samples of 50 microliter washed blood cells. Released histamine is bound to microfibres and measured after removal of interfering substances by washing. The microfibre method was compared with the conventional leukocyte histamine release assay in 18 allergic patients tested with 10 different allergens. It was found that the same individuals responded with histamine release to the same allergens in both assays, and the number of responders was almost identical. Also the dose-response curves and the cell sensitivity were almost identical, which further substantiated identity between the results obtained by the new microfibre method and the conventional assay. A comparison between the microfibre method and in vivo provocation tests showed good agreement when comparing the number of positive and negative responses in these test. The new method overcomes the problems in allergy testing, where only small amounts of blood are available and many tests have to be carried out.
