A result of between 3–5 seconds is equivocal, whereas the radial artery will not be considered for grafting if the result is longer than 5 seconds. [ 3 ] The utility of the modified Allen's test is questionable, [ 4 ] and no direct correlation with reduced ischemic complications of radial artery cannulation have ever been proven.
If r < 1, then the series converges absolutely. If r > 1, then the series diverges. If r = 1, the root test is inconclusive, and the series may converge or diverge. The root test is stronger than the ratio test: whenever the ratio test determines the convergence or divergence of an infinite series, the root test does too, but not conversely. [1]
Also known as 'effort angina', this refers to the classic type of angina related to myocardial ischemia.A typical presentation of stable angina is that of chest discomfort and associated symptoms precipitated by some activity (running, walking, etc.) with minimal or non-existent symptoms at rest or after administration of sublingual nitroglycerin.

The test was used by Gottfried Leibniz and is sometimes known as Leibniz's test, Leibniz's rule, or the Leibniz criterion. The test is only sufficient, not necessary, so some convergent alternating series may fail the first part of the test. [1] [2] [3] For a generalization, see Dirichlet's test. [4] [5] [6]

The SON-R 5,5-17 was published in 1988. This test replaced the SON-’58 and the SSON. Subsequently, the SON 2.5-7 was revised, which resulted in the publication of the SON-R 2,5-7 in 1998. A short version of this test was published in 2007, the SON-R 2,5-7 [a], which is designed to be administered in non-western countries.
