Search. Also known as an accessory tragus or a branchial cleft remnant, ear tags are usually located in front of the ear or on the cheek, and consist of skin and cartilage. Many tags have a narrow stalk (a pedunculated tag), and some pediatricians may tie a string around the tag to intentionally âstrangleâ it.
Validity. The extent to which a test measures what it is supposed to measure. All tests are designed to measure something; hopefully something specific. If the test does indeed measure what it is intended to measure, then we can say that the test is --------.plit-Half Reliability. A measure of consistency where a test is split in two and the scores for each half of the test is compared with one another. If the test is consistent it leads the experimenter to believe that it is most likely measuring the same thing.
The osmolality urine test measures the concentration of particles in urine. Osmolality (particles per kilogram of water) and osmolarity (particles per liter of solution) are sometimes confused. But for dilute fluids such as urine, they are essentially the same. Osmolality can also be measured using a blood test. Reference from A.D.A.M.
