Serum total protein, also known as total protein, is a clinical chemistry parameter representing the concentration of protein in serum. [1] Serum contains many proteins including serum albumin, a variety of globulins, and many others.
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 ...
Serum protein electrophoresis (SPEP or SPE) is a laboratory test that examines specific proteins in the blood called globulins. [1] The most common indications for a serum protein electrophoresis test are to diagnose or monitor multiple myeloma , a monoclonal gammopathy of uncertain significance (MGUS), or further investigate a discrepancy ...
T-SPOT.TB counts the number of antimycobacterial effector T cells, white blood cells that produce interferon-gamma, in a sample of blood.This gives an overall measurement of the host immune response against mycobacteria, which can reveal the presence of infection with Mycobacterium tuberculosis, the causative agent of tuberculosis (TB).
[5] [8] This is the result of the fact that APC prolongs the aPTT but inhibits thrombin generation. [8] Whereas the aPTT-based APC resistance test only measures the initiation phase of coagulation, the ETP-based test is a global assay and measures the initiation, propagation, and termination phases of coagulation.
The blood tests QuantiFERON-TB Gold In-Tube and T-SPOT.TB use these antigens to detect people with tuberculosis. Lymphocytes from the patient's blood are incubated with the antigens. These tests are called interferon γ tests and are not equivalent. [19] If the patient has been exposed to tuberculosis before, T lymphocytes produce interferon γ ...
Putrino and his colleagues compared blood samples of 268 people. Some had Covid but had fully recovered, some had never been infected, and the rest had ongoing symptoms of long Covid at least four ...
Hyperproteinemia is the state of having overly high levels of protein in the blood. This can occur due to monoclonal gammopathies such as multiple myeloma and after intravenous immunoglobulin has been given. [1] It can result in a falsely low appearing sodium level (hyponatremia). [1]
