Normal of Tests

Laboratory tests are treatments that examine a sample of blood, urine, other body fluid, or tissue to learn more about a person's health. The findings of the test or say will indicate whether or not an individual falls below the usual lab values.

What are normal lab values?

According to the Administration of Foods and Drugs (FDA), normal values for Lab tests are usually given as upper and lower limits because usual values differ from person to person.

Laboratory tests are usually used to detect the cause of symptoms, confirm a diagnosis and test diseases. The data obtained from this test may also be used to rule out, check and monitor the development of a disease and to plan treatment. All results of the laboratory test should be interpreted within the framework of the general health of the patient and used for additional tests or examinations.

A doctor will submit the extracted sample to a testing laboratory. The sample is tested to see how it responds to various compounds. The findings are then returned to the doctor for medical problems. Laboratories may also compare previous tests to see how the situation changes.

Many factors, including sex, age, race, medical background and general health, can influence lab results and changes normal of tests. Effects can also have an effect on food, medications, laboratory procedures, and laboratory improvements. In most cases, patients do not drink, eat and take medications several hours before the trials are performed.

The FDA is the regulatory authority responsible for developing and selling laboratory experiments using market-based test kits and facilities. If the test materials and facilities have been licensed, the federal and state authorities must comply with production and use requirements.
