The test was once part of the World Health Organization (WHO) algorithm for diagnosis of dengue fever, [3] however it is no longer used in the latest WHO guidance. [4] Studies have shown that the tourniquet test has low predictive value for dengue fever and should be used in conjunction with other tests for a reliable diagnosis. [5] [6] [7] [8]
The Hess test or Rumpel-Leede test is a medical test used to assess capillary fragility. [1] It is also called the Tourniquet test . To perform the test, pressure is applied to the forearm with a blood pressure cuff inflated to between systolic and diastolic blood pressure for 10 minutes.
Tests for dengue virus-specific antibodies, types IgG and IgM, can be useful in confirming a diagnosis in the later stages of the infection. Both IgG and IgM are produced after 5–7 days. The highest levels of IgM are detected following a primary infection, but IgM is also produced in secondary and tertiary infections. IgM becomes undetectable ...
This year, the incidence of dengue fever globally has been the highest on record, especially in Latin American countries, where more than 9.7 million dengue cases have been reported. That's twice ...
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 ...
Article says: "The test remains an essential part of the assessment of a patient who may have dengue haemorrhagic fever." Since this is in the context of a statement that a major insurance company has determined that this test is obsolete or unreliable and replaced it by more advanced procedures, we may want to clarify by whom exactly this test is (still) considered essential.
The lack of reagents is having serious consequences on the diagnosis and treatment of dengue, as many patients are forced to wait long periods for test results, delaying appropriate care. Additionally, these shortages compromise hospitals' ability to effectively control the outbreak, increasing the risk of disease spread. [ 55 ]
NS1 antigen test (nonstructural protein 1) is a test for dengue, introduced in 2006. It allows rapid detection on the first day of fever, before antibodies appear some 5 or more days later. [1] It has been adopted for use in some 40 nations. The method of detection is through enzyme-linked immunosorbent assay.
