  2. Erythrocyte sedimentation rate - Wikipedia

    en.wikipedia.org/wiki/Erythrocyte_sedimentation_rate

    In non-inflammatory conditions, plasma albumin concentration, size, shape, and number of red blood cells, and the concentration of immunoglobulin can affect the ESR. Non-inflammatory conditions that can cause raised ESR include anemia, kidney failure, obesity, ageing, and female sex. [7] ESR is also higher in women during menstruation and ...

  3. Polymyalgia rheumatica - Wikipedia

    en.wikipedia.org/wiki/Polymyalgia_rheumatica

    The faster the red blood cells settle, the higher the ESR value (measured in mm/hour), which suggests that inflammation may be present. Many conditions can cause an elevated ESR, so this test alone is not proof that a person has polymyalgia rheumatica. [17] [18] Another test that checks the level of C-reactive protein (CRP) in the blood may ...

  4. Rouleaux - Wikipedia

    en.wikipedia.org/wiki/Rouleaux

    The flat surface of the discoid RBCs gives them a large surface area to make contact with and stick to each other; thus forming a rouleau. They occur when the plasma protein concentration is high, and, because of them, the ESR (erythrocyte sedimentation rate) is also increased. This is a nonspecific indicator of the presence of disease.

  5. Macrophage activation syndrome - Wikipedia

    en.wikipedia.org/wiki/Macrophage_activation_syndrome

    Despite marked systemic inflammation, the erythrocyte sedimentation rate (ESR) is paradoxically depressed, caused by low fibrinogen levels. The low ESR helps to distinguish the disorder from a flare of the underlying rheumatic disorder, in which case the ESR is usually elevated. A bone marrow biopsy or aspirate usually shows hemophagocytosis.

  6. Acute infectious thyroiditis - Wikipedia

    en.wikipedia.org/wiki/Acute_infectious_thyroiditis

    Blood tests of thyroid functions including TSH, T4 and T3 are usually normal [3] Ultrasonographic examination often shows the abscess or swelling in thyroid; Gallium scan will be positive; Barium swallow will show fistula connection to the piriform sinus and left lobe; Elevated white blood cell count [3] Elevated erythrocyte sedimentation rate [3]

  7. Rheumatoid arthritis - Wikipedia

    en.wikipedia.org/wiki/Rheumatoid_arthritis

    Other blood tests are usually done to differentiate from other causes of arthritis, like the erythrocyte sedimentation rate (ESR), C-reactive protein, full blood count, kidney function, liver enzymes and other immunological tests (e.g., antinuclear antibody/ANA) are all performed at this stage.

  8. Eosinophilic pneumonia - Wikipedia

    en.wikipedia.org/wiki/Eosinophilic_pneumonia

    Laboratory tests typical of chronic eosinophilic pneumonia include increased levels of eosinophils in the blood, a high erythrocyte sedimentation rate, iron deficiency anemia, and increased platelets. A chest X-ray can show abnormalities anywhere, but the most specific finding is increased shadow in the periphery of the lungs, away from the heart.

  9. Polyarteritis nodosa - Wikipedia

    en.wikipedia.org/wiki/Polyarteritis_nodosa

    No specific lab tests exist for diagnosing polyarteritis nodosa. Diagnosis is generally based on the physical examination and a few laboratory studies that help confirm the diagnosis: [citation needed] CBC (may demonstrate an elevated white blood count) ESR (elevated)
