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.
The test is reported in two parts, the initial standing up of the patient (positive or negative based on rapid filling) and the second phase once the tourniquet is removed (positive or negative based upon rapid filling). [citation needed]
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.

Here "T+" or "T−" denote that the result of the test is positive or negative, respectively. Likewise, "D+" or "D−" denote that the disease is present or absent, respectively. So "true positives" are those that test positive (T+) and have the disease (D+), and "false positives" are those that test positive (T+) but do not have the disease (D ...
It presents as a distal shower of petechiae that occurs after the release of pressure from a tourniquet or sphygmomanometer. [ 1 ] : 824 [ 2 ] The blood pressure cuff should be inflated to a pressure between the systolic and diastolic pressures and kept inflated for 5 minutes.
Another method of achieving constriction of the supplying artery is a tourniquet - a band tied tightly around a limb to restrict blood flow. Tourniquets are routinely used to bring veins to the surface for cannulation, though their use in emergency medicine is more limited. Many armies carry a tourniquet as part of their personal first aid kit.
