Diagnostic Tests for Nosebleeds

Diagnostic Test list for Nosebleeds:

The list of diagnostic tests mentioned in various sources as used in the diagnosis of Nosebleeds includes:

  • Physical examination
    • Blood pressure. High blood pressure may be a cause of the bleeding nose
    • After nasal trauma, must always inspect inside the nose for a blood clot in the septum because it may be later complicated by abscess formation and collapse of the nasal septum causing a permanent deformity
    • Determine where the bleeding is coming from - e.g. from Little's area in the nose (the front part of the nasal septum) or further up the nasal passageway. Ninety percent of bleeding noses result from bleeding from Little's area. Bleeding from this area is usually not a serious problem. However when the bleeding is from the back of the nasal passageway, one must always consider the possibility of a nasal cancer.
    • Full examination of the ears, nose and throat
    • Feel the lymph nodes in the neck for enlargement
    • Examine for petechial body rash (pinhead size red rash) which is common in any disorder that might cause thrombocytopenia (reduced platelets)
    • Examine for bruises which may suggest Hemophilia, Christmas disease, platelet disorders or disseminated intravascular coagulation
    • Examine for bleeding gums - if bleeding gums is present with skinbruises suggests platelet disorders or disseminated intravascular coagulation.
    • Examine for swollen painful joints typical of Hemophilia or Rheumatoid arthritis
    • Examine for enlarged spleen which may suggest Hodgkin's disease, leukemia, thrombocytopenic purpura or aplastic anemia
  • Blood tests
    • Full blood count with platelet count and ESR
    • Electrolytes
    • Fasting blood sugar. Diabetes is associated with bleeding from areas further back in the nasal passages
    • Serum ANCA for Wegener's granulomatosis
    • Coagulation profile, if recurrent nose bleeds with prothrombin time, partial thromboplastin time (PTT), bleeding time, platelet count
    • More sophisticated bleeding disorder tests depending on suspicion - e.g. Hemophilia screening, von Willebrand's disease, platelet function studies, platelet antibodies.
    • Raised Immunoglobulin levels and presence of certain autoantibodies may suggest diagnosis of Sjogren's syndrome which causes a dry nose and consequently an increased risk of bleeding nose - e.g. Rheumatoid factor, antinuclear antibodies, antimitochondrial antibodies, Anti-Ro (SSA) antibodies.
  • Radiological investigations
    • Sinus X-Ray
    • CT Scan of nasal cavity and sinuses may be indicated
  • Nasal smear and culture - for bacteria and fungi. Nasal infection may cause nose bleeds.
  • Nasopharyngoscopy - by Ears, nose and Throat specialist may be indicated.
  • Schirmer tear test, if have dry eyes and nose - a strip of filter paper is placed on the inside of the lower eyelid and wetting of less than 10mm in 5 minutes indicated defective tear production and thus dry eyes. This test will help diagnose Sjogren's syndrome.
  • Bone marrow examination - may be required to exclude secondary causes of thrombocytopenia (reduced platelets) e.g. leukemia, aplastic anemia.
