The rapid plasma reagin test (RPR test or RPR titer) is a type of rapid diagnostic test that looks for non-specific antibodies in the blood of the patient that may indicate an infection by syphilis or related non-venereal treponematoses. It is one of several nontreponemal tests for syphilis (along with the Wassermann test and the VDRL test).
The rapid plasma reagin (RPR) test uses the same antigen as the VDRL, but in that test, it has been bound to several other molecules, including a carbon particle to allow visualization of the flocculation reaction without the need of a microscope. Many other medical conditions can produce false positive results, including some viruses ...
Nontreponemal tests are screening tests, very rapid and relatively simple, but need to be confirmed by treponemal tests. [1] Centers for Disease Control and Prevention (CDC)-approved standard tests include the VDRL test (a slide test), the rapid plasma reagin (RPR) test (a card test), the unheated serum reagin (USR) test, and the toluidine red ...
Progressive disease (PD): At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions; Evaluation of non-target lesions. Complete response (CR): Disappearance of all non-target lesions and normalization of tumor marker level
In patients with significant signs or symptoms, treat can involve chemotherapy, immunotherapy, or chemoimmunotherapy. [4] The most appropriate treatment is based on the individual's age, physical condition, and whether they have the del(17p) or TP53 mutation. [14] As of 2024, the recommended first-line treatments include:
Serology is the scientific study of serum and other body fluids.In practice, the term usually refers to the diagnostic identification of antibodies in the serum. [1] Such antibodies are typically formed in response to an infection (against a given microorganism), [2] against other foreign proteins (in response, for example, to a mismatched blood transfusion), or to one's own proteins (in ...
In 2007, the U.S. Government Accountability Office published an examination of the deaths of several teens attending programs in which endurance tests were part of their treatment. In testimony before Congress, GAO officials quoted from one program brochure, which advertised that the first five days were “days and nights of physical and ...
Conventionally, a leukocytosis exceeding 50,000 WBC/mm 3 with a significant increase in early neutrophil precursors is referred to as a leukemoid reaction. [2] The peripheral blood smear may show myelocytes, metamyelocytes, promyelocytes, and rarely myeloblasts; however, there is a mixture of early mature neutrophil precursors, in contrast to the immature forms typically seen in acute leukemia.
