Due to a major malfunction on the part of our reagent supplier, the D-dimer assay will not be available at UIHC for an indeterminate period of time.  For now, samples will be run at the VA hospital.  There will be some delay in service.  The reference ranges are different and will be noted along with the result.  Thank you for your patience.  Questions can be directed to Ronald Feld, Ph.D., (6-1759).
