Chromogenic Factor IX Assay in Laboratory Diagnosis and Monitoring of Treatment in Hemophilia B – To be aware of Challenges
In the Tuesday afternoon session entitled Chromogenic Factor IX Assay in Laboratory Diagnosis and Monitoring of Treatment in Hemophilia B – To be Aware of Challenges, Jovan Antovic presents data comparing one-stage assays with chromogenic assays for quantifying clotting factor activity, focusing on the challenges presented by their use in diagnosis.
In the Tuesday afternoon session entitled Role of Chromogenic Assays in Hemophilia Diagnosis, Annette Bowyer explains how to set up chromogenic assays for FVIII and FIX, covering technical aspects such as calibration, accuracy, and quality control in the context of these assays, as well as the cost implications of using them appropriately.
In the Tuesday afternoon session entitled Role of Chromogenic Assays in Hemophilia Diagnosis, Elizabeth Duncan presented a comparison of clotting assays versus the chromogenic assay in quantifying FVIII, highlighting genotype and phenotype discrepancies and reverse discrepancies.
In the Monday afternoon session entitled Rare Bleeding Disorders, Gillian Gidley reviews the genotypes and phenotypes associated with FXI deficiency, shows data on different diagnostic assays, and covers recommendations for management of patients with FXI deficiency.
In the Monday morning session entitled Inhibitors: Clinical Aspects, Jan Astermark described the different diagnostic assays laboratories can carry out to measure inhibitors.
