Peripheral artery disease most commonly affects the legs, but other arteries may also be involved, such as those of the arms, neck, or kidneys. [4] [17] Peripheral artery disease (PAD) is a form of peripheral vascular disease. Vascular refers to both the arteries and veins within the body. PAD differs from peripheral veinous disease. PAD means ...
Next check for rubor of dependency. Sit the patient upright and observe the feet. In normal patients, the feet quickly turn pink. If, more slowly, they turn red like a cooked lobster, suspect ischemia. Brodie-Trendelenburg test (assessment of valvular competence if varicose veins are present): One leg at a time.
Buerger's test is performed in an assessment of arterial sufficiency. It is named after Leo Buerger . The vascular angle , which is also called Buerger's angle , is the angle to which the leg has to be raised before it becomes pale, whilst lying down .
Resting ABPI is insensitive to mild PAD. [8] Treadmill tests (6 minute) are sometimes used to increase ABPI sensitivity, [9] but this is unsuitable for patients who are obese or have co-morbidities such as Aortic aneurysm, and increases assessment duration. Lack of protocol standardisation, [10] which reduces intra-observer reliability. [11]
Testing involves a visual inspection of the equipment and verification that power cables are in good condition. Additionally, other tests may be done when required, such as a verification of earthing (grounding) continuity, a test of the soundness of insulation between the current-carrying parts, and a check for any exposed metal that could be ...
A lateral flow test (LFT), [1] is an assay also known as a lateral flow device (LFD), lateral flow immunochromatographic assay, or rapid test. It is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment.

Because the test pad reaction is dependent on pH, false positive results can occur if the urine is highly alkaline. [60] [62] Conventional test strips are not sensitive enough to reliably detect microalbuminuria, a condition in which urine albumin levels are slightly elevated, [64] although dipsticks specialized for this measurement exist.
