The Oregon Environmental Laboratory Accreditation Program (ORELAP) accredits qualified laboratories for testing under the Safe Drinking Water Act (SDWA). See below for lists of accredited laboratories and more information about ORELAP.
In 2005, the Oregon Legislature amended ORS 448.150 (pdf) to require certified/accredited drinking water laboratories to report directly to Drinking Water Services any analytical result that exceeds a Maximum Contaminant Level (MCL).
The Centers for Medicare & Medicaid Services (CMS) regulates all laboratory testing (except research) performed on humans in the U.S. through the Clinical Laboratory Improvement Amendments (CLIA). In total, CLIA covers approximately 320,000 laboratory entities. The Division of Clinical Laboratory Improvement & Quality, within the Quality, Safety & Oversight Group, under the Center for Clinical Standards and Quality (CCSQ) has the responsibility for implementing the CLIA Program.
The objective of the CLIA program is to ensure quality laboratory testing. Although all clinical laboratories must be properly certified to receive Medicare or Medicaid payments, CLIA has no direct Medicare or Medicaid program responsibilities.
To report a complaint about a laboratory, contact the appropriate State Agency (PDF) that is found on the State Agency & Regional Office CLIA Contacts page located in the left-hand navigation pane in this section. See the Consumer Complaints FAQ (PDF) on how to file a complaint. Additionally, see the Temporary COVID-19 Testing Sites (PDF) infographic, which advises those receiving laboratory services of things to be aware of to ensure they are receiving quality laboratory testing.
IMPORTANT UPDATE: On November 16, 2023, Section 502 of the Further Continuing Appropriations and Other Extensions Act of 2024 was passed and delayed data reporting requirements for clinical diagnostic laboratory tests (CDLTs) that are not advanced diagnostic laboratory tests, and it also delayed the phase-in of payment reductions under the CLFS from private payor rate implementation. Please see below for the following changes:
We pay for most clinical diagnostic laboratory tests (CDLTs) based off the weighted median of private payor rates (fee schedule). Typically, we update the payment rates using private payor rates every 3 years. This is based on The Protecting Access to Medicare Act (PAMA).
Drug testing laboratories certified by the Department of Health and Human Services receive urine specimens and test them to determine the presence of drugs. They also conduct validity testing to determine if the specimen has been adulterated or substituted.
A laboratory located in the U.S. is only permitted to participate in DOT drug testing only if it is certified by HHS under the National Laboratory Certification Program (NLCP) or in the case of a foreign laboratory, if it is approved for participation by the DOT with respect to Part 40.
As a reminder, only those laboratories identified under the HHS-Certified Laboratories list are permitted to participate in the DOT drug testing program. HHS-Certified Instrumented Initial Testing Facilities are not authorized for use in the DOT drug testing program.
A laboratory participating in DOT drug testing must comply with the requirements in 49 CFR Part 40, as well as, all applicable HHS requirements. While it is important for the laboratory to be familiar with all aspects of 49 CFR Part 40, the laboratory should pay particular attention to the following:
The NFL, in collaboration with the NFLPA, through their respective appointed biomechanical experts, coordinated extensive laboratory research to evaluate which helmets best reduce head impact severity.
The results of the laboratory tests are displayed on the poster below and shared with NFL players, in addition to club medical, training, coaching and equipment staffs to help inform equipment choices. Other factors, in addition to the ranking, should be considered by players when choosing a helmet, including fit, comfort, durability, player position and the player's medical history.
In 2024, the NFL and NFLPA added three position-specific posters, displaying the rankings for top generic (all-position) helmets and position-specific helmets based on additional impact conditions commonly experienced in those positions. The posters, offered for the quarterback, offensive lineman and defensive lineman positions, help players focus on the helmets that are expected to offer them the best protection for their position.
The laboratory test conditions are intended to represent potentially concussive head impacts in the NFL. The results of this study should not be extrapolated beyond the NFL, including to collegiate, high school or youth football.
Discontinued helmets that were worn by less than 1% of players for the past two seasons have been removed from the poster and added to a legacy list. These helmets are still permissible for use and have been color-coded according to the 2024 poster groupings. Helmets in either shade of green may be worn by any player, while those in yellow are not permitted for new players or those who did not wear them during the 2023 season.
The following prohibited helmet models perform poorly in laboratory testing, have been discontinued by the manufacturer, or were produced by companies no longer manufacturing football helmets. All the helmets listed below are prohibited for use on-field by NFL players.

Effective March 1, 2024, Vanderbilt University Medical Center Diagnostic Laboratories will operate under a new name, Vanderbilt Medical Laboratories (VML), with new CLIA certificates. This change reflects a complete transformation of our laboratory operations with many benefits.
Our new 110,000-square-foot diagnostic core laboratory supports the needs of Vanderbilt University Medical Center's inpatient hospitals, outpatient clinics, regional hospitals, and extramural practice customers. Located five miles north of the 21st Avenue Nashville campus, the laboratory has expanded capacity to bring more testing to Vanderbilt, deploy innovative technology, improve patient care, and enhance team collaboration. The laboratory offers an expanded test menu supporting routine and specialized testing and aims to become the preferred reference laboratory provider in the southeast region.
Vanderbilt Health recognizes that diversity is essential for excellence and innovation. We are committed to an inclusive environment where everyone has the chance to thrive and to the principles of equal opportunity and affirmative action. EOE/AA/Women/Minority/Vets/Disabled
The laboratories listed in the table below are those that have complete applications submitted for PFAS certification in the state of Wisconsin as of Oct. 21, 2021, but are not yet certified for these matrices.
The DNR cannot endorse any laboratory over another. We recommend that you ask the laboratory about any PFAS accreditations it may hold, the cost of testing, the expected turnaround time for results, what sample collection containers they will provide and if they provide any specific sample collection instructions to follow when collecting a sample.
PFAS are present in many things we use in our everyday life. These chemicals have been widely used to produce products that are water-resistant, stain-resistant, heat resistant and/or oil resistant. Residents sampling their water should be aware that they can accidentally contaminate their water sample during sample collection. For this reason, samplers must wear nitrile gloves (generally provided in the sampling kit from the laboratory) and make sure not to touch anything other than the sample bottles during sample collection. Be sure to read and follow any instructions that come with a water sample kit.
Samplers are also advised to avoid wearing lotion, deodorant, cosmetics, sunscreen, waterproof clothing, stain-resistant clothing and clothing washed in fabric softener when collecting their sample. Other persons near the sample collection area should do the same or move out of the sampling area.
The search results are based on information provided by the laboratory offering the test at the time of submission for review. Specifically, inclusion in a particular search output does not guarantee that the test is still being offered by the laboratory, or that the laboratory will accept your sample. You need to contact the laboratory directly for that information.
The default setting for all fields is such that when you enter multiple search terms, results will be returned that contain any of the terms you entered either in their entirety or as part of a longer word.

These minimum analyte lists were developed based on the potential for these chemicals to be found in Michigan, the availability of the chemical standards used for testing, and the ability of available laboratories to test for these PFAS compounds. These lists include PFAS that can be tested for in drinking water using United States Environmental Protection Agency (U.S. EPA) Method 533 or 537.1, which are the only methods appropriate when analyzing drinking water samples. Other testing methodologies may be used to test for PFAS in other media (not drinking water).
