Posterior Vitreous Detachment (PVD) is a natural change that occurs during adulthood, when the vitreous gel that fills the eye separates from the retina, the light-sensing nerve layer at the back of the eye.Download Fact Sheet Large-Print Version Diagnostic testing. Posterior vitreous detachment is usually diagnosed with a dilated eye examination. However, if the vitreous gel is very clear, it may be hard to see the PVD without additional testing, such as optical coherence tomography (OCT) or ocular ultrasound (see Figure 2).

The Pap (Papanicolaou) Test The Pap test is a procedure used to collect cells from the cervix so that they can be looked at under the microscope to find cancer and pre-cancer. The health care professional first places a speculum inside the vagina. The speculum is a metal or plastic instrument that keeps the vagina open so that the cervix can be seen clearly.

- From Wikipedia, the free encyclopedia. Ventilator-associated pneumonia (VAP) is a type of lung infection that occurs in people who are on breathing machines in hospitals. As such, VAP typically affects critically ill persons that are in an intensive care unit (ICU). VAP is a major source of increased illness, and death.s an example, some institutions may require one clinical symptoms such as shortness of breath, one clinical sign such as fever, plus evidence on chest xray and in tracheal cultures. There is no gold standard for getting cultures or other evidence of bacterial, viral, or fungal culprit.

- EVAP TEST ADDED TO THE SMOG CHECK. Passenger vehicles built between 1976 and 1995 will require a test of their fuel evaporative control (EVAP) system. The test is called the Low-Pressure Fuel Evaporation Test (LPFET). What is the EVAP test for? The EVAP system is designed to capture fuel vapors (hydrocarbons) from the vehicle.

Peripheral vascular examination A peripheral vascular examination is a medical examination to discover signs of pathology in the peripheral vascular system. It is performed as part of a physical examination, or when a patient presents with leg pain suggestive of a cardiovascular pathology. Venous refill with dependency (should be less than 30 seconds) - the vein should bulge outward within 30 seconds of elevation for one minute. 2  Buerger's test (assessment of arterial sufficiency): 3  With the patient supine, note the colour of the feet soles.

Vestibular evoked myogenic potential The vestibular evoked myogenic potential (VEMP or VsEP) is a neurophysiological assessment technique used to determine the function of the otolithic organs (utricle and saccule) of the inner ear. It complements the information provided by caloric testing and other forms of inner ear (vestibular apparatus) testing.here are six receptor organs located in the inner ear: cochlea, utricle, saccule, and the lateral, anterior, and posterior semicircular canals. The cochlea is a sensory organ with the primary purpose to aid in hearing.

Pulse Volume Recording Pulse volume recording (PVR) is a non-invasive imaging test that evaluates the lower or upper extremity blood flow. They are actually the more complete form of ankle brachial index, because they test more areas of the limb and not just the flow at the end. Pulse volume recording is a functional test. This means that it does not examine specific blood vessels, but rather assesses the sum of all blood flow to the examined limb.

- Two bacterial broth cultures, showing a positive result (left side) and a negative result (right side) for the VP test. Voges–Proskauer /ˈfoʊɡəs ˈprɒskaʊ.ər/ or VP is a test used to detect acetoin in a bacterial broth culture. The test is performed by adding alpha-naphthol and potassium hydroxide to the Voges-Proskauer broth which has been inoculated with bacteria. A cherry red color indicates a positive result, while a yellow-brown color indicates a negative result. The test depends on the digestion of glucose to acetylmethylcarbinol. If glucose is being broken down, it will react with alpha-naphthol (VP reagent #1) and potassium hydroxide (VP reagent #2) to form a red color. Alpha-naphthol and potassium hydroxide are chemicals that detect acetoin.
