Urinalysis Test Results

Receiving test results Your doctor may contact you by phone or email to discuss the findings of your test. A copy of the urinalysis lab test result can sometimes be obtained by mail or through an online health platform. Results are usually available within a few business days. Interpreting test results Your test report will list the types of analysis performed on your urine sample. It may include a summary of any specific findings with a written description of results from microscopic and visual examination. For any measurements taken, the test report may show your levels alongside a reference range. This range reflects the laboratory’s expected values for a healthy person. Reference ranges often vary slightly between different laboratories because they can employ different measurement methods. Because these ranges may differ by the laboratory, you should read your test report carefully and discuss it with your doctor. Urinalysis tests are interpreted based on the results of the different components of the test and other factors, including your symptoms and overall health. Your doctor will look for any abnormalities in the test. The significance of an irregularity in the urine’s physical, chemical, or microscopic characteristics might vary depending on your health history and current situation. Many different health conditions can cause abnormal results on a urinalysis test. Examples of conditions that may lead to abnormal results include: Urinary tract infections (UTIs) Kidney stones Diabetes Trauma to the kidneys Liver diseases Some types of cancer Certain medications, vitamins, and supplements can cause irregularities in urinalysis results. Some foods can also cause changes to the color and odor of urine that may lead to an irregularity during urinalysis. It is important to talk with your health care provider to understand the details of your urinalysis test and what the results mean for your health. Are test results accurate? Urinalysis results are generally considered accurate, but they are not infallible. To achieve reliable results, laboratories must follow best practices while collecting, processing, and analyzing urine samples. Even when those best practices are followed, other factors may impact the reliability of a urinalysis test result: Foods and drugs: Certain foods and medicines are known to cause color or smell changes to urine and may interfere with the interpretation of test results. Problems with the sample: Improper collection might lead to contamination or inaccurate results. For example, failing to collect all your urine during 24-hour sample collection or failing to clean the urethral opening before obtaining a one-time sample can prevent proper laboratory analysis. Do I need follow-up tests? In the event of an atypical result, additional testing is usually recommended. A urinalysis on its own often does not provide enough information to the health care provider about the underlying cause. Depending on the type of abnormal result that was found, other tests may be ordered to help confirm or rule out a specific diagnosis. Questions for your doctor about test results The following questions may be useful when you review your urinalysis test results with your doctor: Were any parts of my urinalysis test abnormal? Do the test results help address why I might be having symptoms? Are any follow-up tests needed in this situation? Do you recommend any treatments or lifestyle changes based on these results? Should I have a urinalysis test again in the future?

Quest policy is based upon three primary rules:

  • Rule 1: Individuals should have the right to privacy while using the toilet and urinating into a sample container.
  • Rule 2: Toilets are designed for one person at a time use. Additionally, they do not want to create an awkward situation with their staff members.
  • Rule 3: At Quest Diagnostics, they do not provide laboratory personnel responsible for monitoring an individual's urine while urinating in a toilet. This task is handled by the individual collecting the sample.

Quest also believes that all individuals have the right to privacy while urinating into a container at home. As such, they should be able to handle their collection and transportation without outside assistance or supervision.

Some testing companies require staff to watch an individual collect a sample, but this is not what Quest practices.

FAQ for Synthetic Drug Testing

This section covers frequently asked questions about testing for common synthetic drugs, including cannabinoids and synthetic stimulants like “bath salts.” It lists the specific compounds Quest Diagnostics tests for, as well as answers to other questions.

What are synthetic drugs or designer drugs?

Synthetic drugs or designer drugs don’t come from controlled plant sources like cocaine and marijuana do. Instead, they’re lab-created in an attempt to mimic those drugs. They include synthetic marijuana and synthetic stimulants like “bath salts.” Illegal drug manufacturers constantly alter their formulae to try to evade drug tests. Synthetic marijuana can be up to 50 times more potent than its natural counterpart.

How does Quest Diagnostics test for synthetic drugs?

Quest Diagnostics works with the oil industry and several government bodies to refine the list of tested-for compounds. Next, the company works with employers to test employees for the offending drugs.

Which synthetic drugs does Quest Diagnostics detect?

Quest tests for synthetic cannabinoids by detecting these compounds: AB-FUBINACA, AB-CHMINACA, ADB- PINACA, AB-PINACA/5F-AB-PINACA, UR -144/ XLR11, ADBICA, BB-22, AKB- 48 (APINACA), JWH-073, JWH-018/AM-2201, AND PB-22/5F-PB-22.

They also test for synthetic stimulants  known as “bath salts” (and by other names) by detecting the following compounds: Butylone, alpha- PVP, Flephedrone (4-Fluoromethcathinone), Mephedrone, MDPV, Methedrone, Pentylone, Pentedrone, and Methylone.

Can a synthetic drug test be included with a standard drug test?

Because of different testing methods, a synthetic drug test must be ordered separately from a standard drug test.

Consider all drug testing specimen types

Potential subversion of the urine drug testing process is one reason that alternative specimens – hair and oral fluid – are being considered for federally-regulated drug testing programs. Urine drug testing is not directly observed; but because hair and oral fluid collections are observed, the possibility of subversion is also significantly reduced. Recent data from the Quest Diagnostics Drug Testing Index™ suggests the effectiveness of oral fluid in detecting drug use – even though it is generally acknowledged that it has a slightly shorter window of detection (depending on the drug/metabolite) – as compared to urine.

In regards to the collection of oral fluid specimens, the Proposed Federal Oral Fluid Mandatory Guidelines issued in May 2015 propose equivalent standards for oral fluid collections as urine collections (e.g., Sections 5.1, 5.2, and 8.1). While many, but not all, private sector employers “self-collect” oral fluid, this is not a uniform process and some employers prefer that oral fluid collection be separated from the hiring manager or supervisor as the proposed Federal guidelines envisage. Whether the collection is observed or not, our position is that SVT remains a critical component of the oral fluid testing process to ensure an adequate and proper collection.

Can You Cheat With Synthetic Urine Quest Diagnostics Drug Screening?

If you’re one of the unlucky souls with a job that requires drug testing, then you should probably care about this.

Quest Diagnostics is one of the largest and most popular companies for performing pre-employment drug screenings on potential employees.

If your urine has any traces of fake pee or other adulterants in it, they will know because their lab equipment can detect these chemicals.

So if you want to keep your job, make sure that when you go into the office to be tested, all liquids are from natural sources and not anything else; otherwise, you’ll end up losing your job if caught with fake pee in a drug screening.
