    Versiti Diagnostic Labs provides specialized testing for the evaluation of disorders involving abnormal numbers of blood cells, including immune and non-immune disorders of red blood cells, white blood cells and platelets. 

    Available evaluations include:

    • Pancytopenia
    • Leukopenia
    • Thrombocytopenia
    • (Auto) Immune thrombocytopenia (ITP)
    • Drug-induced cytopenia (anemia, thrombocytopenia, leukopenia)
    • Anemia, including iron deficiency, other nutritional anemias and autoimmune hemolytic anemias
    • Leukocytosis
    • Thrombocytosis (reactive and essential thrombocythemia)
    • Polycythemia (suspected primary – PV, and secondary)
    • Myelodysplasia
    • Myeloproliferative disorders (myelofibrosis, polycythemia vera, essential thrombocythemia
    • Hematology in pregnancy (gestational thrombocytopenia, ITP)
    • Monoclonal gammopathy of undetermined significance (MGUS)

    We also provide comprehensive functional and genetic testing in support of inherited and immune platelet and neutrophil disorders. Our targeted focus includes:

    • Drug-induced thrombocytopenia, including HIT
    • Idiopathic thrombocytopenia (ITP)
    • Fetal and neonatal alloimmune thrombocytopenia (FNAIT)
    • Allo- and autoimmune neutropenia
    • Drug-induced neutropenia
    • Neonatal alloimmune neutropenia

    1800 - VWD Diagnostic Evaluation

    Reflexive algorithm always includes: FVIII Activity, VWF Antigen, VWF GPIbM Activity, and VWF Collagen III Binding. Reflex testing may include: VWD Type 2B Binding, VWD Type 2N Binding, VWF Propeptide Antigen, and/or VWF Quantitative Multimer

    5502 - Heparin-Induced Thrombocytopenia - PEA

    This test is designed to detect heparin-dependent platelet antibodies in the serum from patients suspected of having Heparin-Induced Thrombocytopenia (HIT).

    1280 - VWF Collagen IV Binding

    This assay tests the capacity of platelet adhesion at sites of blood vessel injury and can identify qualitative binding issues.

    1070 - VWF GPIbM Activity

    This ristocetin-independent activity assay is an alternative to VWF Ristocetin Cofactor Activity with superior precision and sensitivity.

    5703 - Neonatal Alloimmune Thrombocytopenia (NAIT)-Initial Paternal

    This order set includes: Platelet Antigen Genotyping Panel. To complete this workup, order Neonatal Alloimmune Thrombocytopenia (NAIT)-Initial Screening Maternal with Paternal (test code 5603) for maternal sample.

    5544 - Platelet Autoantibodies

    This assay detects direct and indirect glycoprotein-specific antibodies in eluates prepared from washed patient platelets.
