The tourniquet test is a clinical assessment used to evaluate capillary fragility and the tendency to bleed. To perform the test, a tourniquet or a blood pressure cuff is applied to the upper arm, inflated to a certain pressure, and left in place for a few minutes. After releasing it, the skin is examined for petechiae or purpura; the presence of these small red or purple spots indicates increased capillary fragility, which may suggest disorders such as thrombocytopenia or vascular issues. A negative result, with no petechiae, indicates normal capillary integrity.

How can a tourniquet affect a blood test?
A tourniquet can affect a blood test by temporarily restricting blood flow, which may lead to hemoconcentration. This can cause an increase in the concentration of certain substances in the blood, such as proteins and electrolytes, potentially skewing test results. Additionally, prolonged application of a tourniquet can cause the release of potassium from cells, falsely elevating potassium levels in the sample. It's important for healthcare providers to apply and remove the tourniquet properly to minimize these effects.
