The Apley grind test or Apley test is used to evaluate individuals for problems in the meniscus of the knee. In order to perform the test, the individual lays face-down on an examination table and flexes a knee to a ninety degree angle. The examiner then places his or her own knee across the posterior aspect of the patient's thigh. The [tibia]] is then compressed onto the knee joint while being externally rotated. If this maneuver produces pain, this constitutes a "positive Apley test" and damage to the meniscus is likely. The Apley test is named for Alan Graham Apley (1914-1996), a British orthopedic surgeon. ...more on Wikipedia about "Apley grind test"

The Arneth count or Arneth index describes the nucleus of a type of white blood cell called a neutrophil in an attempt to detect disease. Neutrophils typically have two or three lobes. In general, older neutrophils have more lobes than younger neutrophils. The Arneth count determines the percentage of neutrophils with one, two, three, four, and five or more lobes. Individuals who have a larger percentage of neutrophils with fewer lobes have a left shift which can be indicative of disease processes such as infection. Individuals with a larger percentage of neutrophils with more lobes have a right shift and most commonly have diseases such as vitamin B12 or folate deficiency. The Arneth count is not commonly used in modern medicine. ...more on Wikipedia about "Arneth count"
