More Lab Results:

  • Immunoglobulins: note study done after IVIG infusions begun
    • Ig A: 100 (68-378 mg/dL)
    • Ig G: 875 (694-1617 mg/dL)
    • Ig M: 38.5 (53-334 mg/dL)

  • DIC workup:
    • FSP: <10 (0-10 ug/mL)
    • D-Dimer: <0.5
    • Fibrinogen: 271(150-400 mg/dL)

  • SPEP:
    • Cryoglobulin negative
    • Albumin: 4.6 (3.5-5 g/dL)
    • Alpha 1: 0.17 (0.1-0.4 g/dL0
    • Alpha 2: 0.65 (0.4-1 g/dL)
    • Beta: 0.91 (0.5-1.2 g/dl)
    • Gamma: 1.36 (0.5-1.6 g/dl)
    • No abnormal discrete band noted
    • UPEP: No abnormal discrete band noted
    • Reticulated Platelet: (5-15%)
    • Platelet count: 9K, Retic Plt %: 58%
    • Interpretation: The markedly elevated RP% is most consistent with severe peripheral platelet destruction such as seen in ITP, TTP, or DIC, or less commonly with platelet sequestration due to splenomegaly.
    • Platelet antibody screen in serum: negative
    • Presence of H-J bodies on smear makes accessory spleen unlikely - no splenic uptake on L/S scan
