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 tourniquet test, which is particularly useful in settings where no laboratory investigations are readily available, involves the application of a blood pressure cuff at between the diastolic and systolic pressure for five minutes, followed by the counting of any petechial hemorrhages; a higher number makes a diagnosis of dengue more likely.
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.

The blanching skin test is used to determine if a rash or discoloration disappears when pressure is applied, which may be a sign of another illness.
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 Since this is in the context of a statement that a major insurance company has determined that this test is obsolete or unreliable and replaced it by more advanced procedures, we may want to clarify by whom exactly this test is (still) considered essential.
Dengue fever is a mosquito-borne disease caused by dengue virus, prevalent in tropical and subtropical areas. It is frequently asymptomatic; if symptoms appear they typically begin 3 to 14 days after infection.
Dengue virus (DENV) is the cause of dengue fever.It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. [1] [2] Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, [3] [4] [5] all of which can cause the full spectrum of disease. [1]
