    3. See Drug Induced Platelet Dysfunction
  3. Vascular Disorders
    1. See Blood Vessel Wall Bleeding Disorders

VIII. Labs: Initial

  1. Complete Blood Count with platelets
  2. Peripheral Blood Smear
  3. ProTime (PT) with INR
  4. Partial Thromboplastin Time (PTT)
  5. Comprehensive metabolic panel (Liver Function Tests and Renal Function tests)

IX. Labs: Based on initial testing

  1. Normal PT, PTT, and Platelet Count/morphology
    1. Obtain labs
      1. Von Willebrand Factor Antigen
      2. Von Willebrand Factor Activity (risocetin Cofactor activity)
      3. Factor VIII Level
      4. AVOID Platelet Function Closure Time (PFCT, Platelet Function Analyzer-100)
        1. No longer recommended due to false negatives in less than severe cases of Von Willebrand
    2. Abnormal labs
      1. Von Willebrand Disease (additional testing can identify type)
    3. Normal labs
      1. Refer to hematology for additional evaluation of platelet function disorder
      2. May require light transmission aggregometry
  2. Partial Thromboblastin Time (PTT) abnormality and Normal PT/INR (Intrinsic Clotting Pathway Abnormal)
    1. PTT corrects with a PTT Mixing Study (patient plasma mixed 1:1 with normal plasma)
      1. Obtain Factor VIII, Factor IX, and Factor XI assays
      2. Consider Von Willebrand's testing if low Factor VIII
    2. PTT does not correct with a PTT Mixing Study (mixed with normal blood)
      1. Obtain Lupus Anticoagulant
      2. Obtain Factor VIII Inhibitor
  3. ProTime (PT) or INR abnormal and Normal PTT (Extrinsic Clotting Pathway Abnormal) - uncommon
    1. PT/INR corrects with Vitamin K Supplementation
      1. Replace Vitamin K as needed
      2. Assess for Malnutrition and malabsorption causes of Vitamin K Deficiency
    2. PT/INR does not correct with Vitamin K Supplementation
      1. Obtain Factor VII assay
  4. BOTH ProTime (PT/INR) and Partial Thromboplastin Time (PTT) Abnormal
    1. Causes
      1. Comorbid advanced liver disease
      2. Disseminated Intravascular Coagulation (DIC)
      3. Anticoagulant use (Warfarin or Heparin)
      4. Combined Intrinsic Clotting Pathway and Extrinsic Clotting Pathway
    2. Labs
      1. Liver Function Tests
      2. Fibrinogen level
      3. Factor Assays
  5. Platelet abnormality
    1. See Platelet Bleeding Disorders
    2. See Drug Induced Platelet Dysfunction
    3. See Thrombocytopenia

X. Management: Hematology Consultation indications

  1. Significant finding on testing
  2. Nondiagnostic results with high clinical suspicion
  3. Preoperative concern for Bleeding Disorder

Definition (MEDLINEPLUS)

Normally, if you get hurt, your body forms a blood clot to stop the bleeding. For blood to clot, your body needs cells called platelets and proteins known as clotting factors. If you have a bleeding disorder, you either do not have enough platelets or clotting factors or they don't work the way they should.

Bleeding disorders can be the result of other diseases, such as severe liver disease. They can also be inherited. Hemophilia is an inherited bleeding disorder. Bleeding disorders can also be a side effect of medicines.
