  2. Reference ranges for blood tests - Wikipedia

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

    Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...

  3. Schumm test - Wikipedia

    en.wikipedia.org/wiki/Schumm_test

    The Schumm test (shoom) is a blood test that uses spectroscopy to determine significant levels of methemalbumin in the blood. A positive result could indicate intravascular hemolysis. [1] [2] The Schumm test was named for Otto Schumm, a German chemist who lived in the early 20th century. [citation needed] A positive test result occurs when the ...

  4. Serum-ascites albumin gradient - Wikipedia

    en.wikipedia.org/wiki/Serum-ascites_albumin_gradient

    A high gradient (> 1.1 g/dL, >11 g/L) indicates the ascites is due to portal hypertension, either liver related or non-liver related, with approximately 97% accuracy. [2] This is due to increased hydrostatic pressure within the blood vessels of the hepatic portal system , which in turn forces water into the peritoneal cavity but leaves proteins ...

  5. Blood residue - Wikipedia

    en.wikipedia.org/wiki/Blood_residue

    Blood residue are the wet and dry remnants of blood, as well the discoloration of surfaces on which blood has been shed. In forensic science, blood residue can help investigators identify weapons, reconstruct a criminal action, and link suspects to the crime. [1] Analysis of blood residue is also an important technique in archeology. [2]

  6. Osmol gap - Wikipedia

    en.wikipedia.org/wiki/Osmol_gap

    The osmol gap is typically calculated with the following formula (all values in mmol/L): = = ([+] + [] + []) In non-SI laboratory units: Calculated osmolality = 2 x [Na mmol/L] + [glucose mg/dL] / 18 + [BUN mg/dL] / 2.8 + [ethanol/3.7] [3] (note: the values 18 and 2.8 convert mg/dL into mmol/L; the molecular weight of ethanol is 46, but empiric data shows that it does not act as an ideal ...

  7. Thromboelastometry - Wikipedia

    en.wikipedia.org/wiki/Thromboelastometry

    Whole blood TEM is sensitive to haemostasis affecting agents such as plasma expanders or acidosis while the effects of these agents are hardly identified by plasma based laboratory tests. TEM-guided transfusion of blood products or factor concentrates in cardiac , hepatic and major orthopedic surgery is the main application of the method.

  8. White blood cell differential - Wikipedia

    en.wikipedia.org/wiki/White_blood_cell_differential

    A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...

  9. Coagulation testing - Wikipedia

    en.wikipedia.org/wiki/Coagulation_testing

    Tests in platelet rich plasma (close to real conditions in the body, but restrictions as to the terms of work), Tests in whole blood (the most adjusted to human physiology; the test can be started immediately; but the least convenient due to terms of blood storage and difficulties of the results' interpretation).
