You may have been directed here by your lab's website in order to provide you with background information about the test s you had performed. You will need to return to your lab's website or portal, or contact your healthcare practitioner in order to obtain your test.

Lab Tests Online is an award-winning patient education website offering information on laboratory tests. The content on the site, which has been reviewed by laboratory scientists and other medical professionals, provides general explanations of what might mean for each test listed on the site, such as what a high or low value might suggest to your healthcare practitioner about your health or medical condition.

The reference ranges for your tests can be found on your laboratory report. They are typically found to the right of your. If you do not have your lab report, consult your healthcare provider or the laboratory that performed the test s to obtain the reference range.

Positive screening tests for marijuana are presumptive. This is because all drug screening tests have the potential for false-positive. Therefore, screening tests that are positive are often confirmed with a second test, which is referred to as a confirmatory test.

Confirmatory tests are usually more sensitive and specific than screening tests. Confirmatory testing is usually performed with an instrument called a mass spectrometer. Additional testing may also be performed to identify whether any substance has been added to the urine sample, such as water, bleach, or other types of chemicals adulterants in an attempt to interfere with the test result. If adulteration is Marijuana blood test detection, the test may be reported as invalid or adulterated.

Urine samples may also be identified as dilute. Dilute urine may be produced if an individual drinks large amounts of water or other liquids prior to testing. Dilute urine may also result from some medical conditions. If an individual adds liquid such as water to a urine sample, this may also cause dilute urine. It may not always be possible to determine how the urine was diluted.
