  2. Erythrocyte sedimentation rate - Wikipedia

    en.wikipedia.org/wiki/Erythrocyte_sedimentation_rate

    The ESR is decreased in polycythemia, hyperviscosity, sickle cell anemia, leukemia, chronic fatigue syndrome, [4] low plasma protein (due to liver or kidney disease) and congestive heart failure. Although increases in immunoglobulins usually increase the ESR, very high levels can reduce it again due to hyperviscosity of the plasma. [5]

  3. Elevated alkaline phosphatase - Wikipedia

    en.wikipedia.org/wiki/Elevated_alkaline_phosphatase

    Tissues that contain high levels of ALP include the liver, bile ducts, and bones. Normal levels of ALP range from (44 to 147) U/L (units per liter) and significantly elevated levels may be an indication of conditions such as various types of cancer, bone diseases such as Paget disease, liver diseases such as hepatitis, blood disorders, or other ...

  4. 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. [16] [17] Another test that checks the level of C-reactive protein (CRP) in the blood may ...

  5. Reference ranges for blood tests - Wikipedia

    en.wikipedia.org/wiki/Reference_ranges_for_blood...

    Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these. [44]

  6. Rheumatoid arthritis - Wikipedia

    en.wikipedia.org/wiki/Rheumatoid_arthritis

    Positive responses to treatment may indicate a better prognosis. A 2005 study by the Mayo Clinic noted that individuals with RA have a doubled risk of heart disease, [199] independent of other risk factors such as diabetes, excessive alcohol use, and elevated cholesterol, blood pressure and body mass index.

  7. 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.

  8. Polycythemia vera - Wikipedia

    en.wikipedia.org/wiki/Polycythemia_vera

    The first is a very high red blood cell count, which is usually identified by elevated levels of hemoglobin or hematocrit; A bone marrow biopsy that shows hypercellularity and abnormalities in megakaryocytes; and; The presence of a mutation in the Janus kinase 2 (JAK2) gene.

  9. Normocytic anemia - Wikipedia

    en.wikipedia.org/wiki/Normocytic_anemia

    A reticulocyte count that is high, normal or low will aid with the classification process. A high reticulocyte count signifies that bone marrow processes are normal. A low reticulocyte count would signify there is a problem at the level of the bone marrow, which produce the stem cells. Acute blood loss would result in a high reticulocyte count ...
