The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]
A hearing test provides an evaluation of the sensitivity of a person's sense of hearing and is most often performed by an audiologist using an audiometer. An audiometer is used to determine a person's hearing sensitivity at different frequencies. There are other hearing tests as well, e.g., Weber test and Rinne test.
The Weber test also uses a tuning fork to differentiate between conductive versus sensorineural hearing loss. In this test, the tuning fork is placed at the top of the skull, and the sound of the tuning fork reaches both inner ears by travelling through bone. In a healthy patient, the sound would appear equally loud in both ears.
This test and its complement, the Weber test, are quick screening tests and are not a replacement for formal audiometry. Recently, its value as a screening test has been questioned. [6] The Rinne test is not reliable in distinguishing sensorineural and conductive loss cases of severe unilateral or total sensorineural loss.
An early warning system (EWS), sometimes called a between-the-flags or track-and-trigger chart, is a clinical tool used in healthcare to anticipate patient deterioration by measuring the cumulative variation in observations, most often being patient vital signs and level of consciousness. [1]

Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The Kraus–Weber test (or K–W test [1]) is a fitness test devised in the 1940s by Hans Kraus and Sonja Weber of New York Presbyterian Hospital. The poor tests results of American children versus children from European countries gained attention in the 1950s from American media, prompting the United States government to establish the Presidential Fitness Test within the following decades.
