Traditionally, a positive modified Allens test (=MAT) had been considered a reliable proof of impaired arterial circulation in the hand. All medical books and plenty of data base for medical students and junior doctors include MAT as an essential procedure before Arterial Blood Gas (=ABG) test is taken. And the instructions are precise and clear: do not perform ABG from the radial artery if modified Allens test is positive. Nonetheless, any doctor that had worked in the UK, can attest that MAT is seldom performed before taking ABG, no matter in emergency department, medics or anaesthetics. A search in the Literature was conducted. We could not find any evidence that demonstrate the usefulness of MAT prior to ABG. We conclude, that unless further evidence is available, MAT should be withdrawn from exams as a rule of thumb prior to performing ABG (at least in the absence of peripheral vascular disease).Downloads
