What is urine analysis?

Whenever a medical expert orders a urine sample from the patient, the collected urine is often sent directly to the laboratory for the procedure called urine analysis. Depending on the doctor's commands, the laboratory technologist will explore everything from color and temperature to the most microscopic crystal formations or blood cells. Urine analysis can detect pregnancy, recreational drug use, diabetes, kidney disease or evidence of infections elsewhere. Normal urine should be light yellow to amber color, but anything closer to the red spectrum can be a warning flag. Coloring can only be caused by the consumption of beetroot or ingestion of food color, but this may also be related to excessive releasing red blood cells. Herotity may indicate crystals or infection. Dark yellow or orange urine is usually a sign of extreme dehydration.

After recording color and clarity, another test of urine analysis can measure a specific weight. Roughly, it would be a relative "thickness" of a urine sample. NOrmal urine is only slightly thicker than clean water due to other minerals and cell tissues melted in it. If urine analysis reveals significantly higher specific weight, the patient may have excessive glucose levels. This could mean an imbalance of blood sugar requiring immediate medical attention.

Most of us only meet with urine analysis during job screening or routine physical tests. The domestic pregnancy test can also be considered as a form of urine analysis, as the user's urine is checked for a reaction to chemicals. If urine samples are to be checked in large or a quick analysis yes/no, the technologist can use the urine gauge. Each gauge for urine analysis contains a specific chemical or a combination of chemicals. The stick immerses in the urine and causes a chemical reaction that may or may not change color. A positive or negative result can be seent within minutes of the test.

Some urine analysis is performed under a microscope because individual cells or crystal formations may be too small to detect. The centrifuge can be used to separate the solid materials from the liquid. These results could detect the presence of kidney stones, weapons of cancer cells or other chronic conditions.

Using urine analysis for screening of jobs has been controversial for many years. The test is primarily used to detect recreational drug use, not other potential health problems. Many illegal and prescription drugs can remain in urine for several days, resulting in positive reading and difficulties in the hiring process.

But urine analysis techniques cannot always distinguish between illegal drug consumption and intake of poppy or over -the -counter medicines. There is always a useful use of rapid urine analysis. Some argued that a system of urinary urine analysis should not be the only PR criterionto determine the appropriateness for employment. Positive results should be handed over for more accurate tests including blood or hair samples.
