Since the first description of cryoglobulinemia in association with the clinical triad of skin purpura, joint pain, and weakness by Meltzer et al. in 1966, [4] [5] the percentage of cryoglobulinemic diseases described as essential cryoglobulinemia or idiopathic cryoglobulinemia (that is, cryoglobulinemic disease that is unassociated with an underlying disorder) has fallen.
Cold sensitive antibodies (CSA) are antibodies sensitive to cold temperature. Some cold sensitive antibodies are pathological and can lead to blood disorder.These pathological cold sensitive antibodies include cold agglutinins, Donath–Landsteiner antibodies, and cryoglobulins which are the culprits of cold agglutinin disease, paroxysmal cold hemoglobinuria in the process of Donath ...
Rheumatoid factor, cryoglobulins, direct antiglobulin test, and cold agglutinin titer results can be positive. Beta-2 microglobulin and C-reactive protein test results are not specific for Waldenström macroglobulinemia. Beta-2 microglobulin is elevated in proportion to tumor mass.
Secondary cold agglutinin syndrome occurs when autoantibodies bind to red blood cells, rendering them subject to attack by the complement system. [17] It is a result of an underlying condition potentially associated with either monoclonal cold-reacting autoantibodies or polyclonal cold-reacting autoantibodies [16] predominantly caused by infection or lymphoproliferative disorders.

Cryoglobulinemic vasculitis is a form of inflammation affecting the blood vessels caused by the deposition of abnormal proteins called cryoglobulins.These immunoglobulin proteins are soluble at normal body temperatures, but become insoluble below 37 °C (98.6 °F) and subsequently may aggregate within smaller blood vessels.
Cancer groups have similar recommendations for BRCA testing, and increasingly urge that the newly diagnosed be tested, too, because the inherited risk can impact choices about surgery and other ...
Cryofibrinogenemia refers to a condition classified as a fibrinogen disorder in which a person's blood plasma is allowed to cool substantially (i.e. from its normal temperature of 37 °C to the near-freezing temperature of 4 °C), causing the (reversible) precipitation of a complex containing fibrinogen, fibrin, fibronectin, and, occasionally, small amounts of fibrin split products, albumin ...
False positive COVID-19 tests—when your result is positive, but you aren’t actually infected with the SARS-CoV-2 virus—are a real, if unlikely, possibility, especially if you don’t perform ...
