Unity Interlaboratory Program

Unity Interlab Program


Participation in a high quality interlaboratory program is as important as ever for laboratories to help ensure the reliability and precision of testing systems.

No program in the world is more powerful and effective at providing information and improving laboratory analytical performance than Bio-Rad's Unity Interlaboratory Program.

Data Management Solutions
  • Be one of thousands of lab site participants worldwide, more than any other interlaboratory program.
  • Participate in Bio-Rad's large interlaboratory groups, which are critical to significant peer comparisons.
  • Recognize analytical process improvement opportunities.
  • Increase confidence in proficiency survey outcomes.
  • Identify unrecognized trends or shifts that may occur between proficiency surveys.
  • Receive on-demand interlaboratory comparison reports for real-time troubleshooting with no applicable deadlines for data submission.
  • Receive routine monthly reports with regular data submission deadlines to maximize peer group sizes.
  • Submit data electronically with the Unity data management software system.
  • Receive reports and other information quickly via the Internet with QCNet™.

Detecting Errors in your Test System

Without a high-quality interlaboratory program, your laboratory may not be aware of gradual or sudden changes in your test system that are often caused by events such as reagent or calibrator reformulations, standardization changes, or instrument software changes. An interlaboratory program can offer awareness of shifts and trends and help verify the reliability of laboratory testing.

Improving Outcomes on Proficiency Surveys

An interlaboratory program can also increase your confidence in proficiency surveys. If your laboratory compares well to other laboratories participating in an interlaboratory program, you are also likely to compare well to other laboratories participating in your proficiency testing program.

Some will argue that a proficiency testing program provides sufficient information to measure overall test system performance. This is simply not true.

  • Proficiency surveys merely provide a snapshot in time and should not be used as a substitute for daily quality control with an interlaboratory program.
  • Acceptable performance on the day of the proficiency testing does not guarantee testing reliability every day.
  • Participation in an interlaboratory program is the best way to be confident in test system performance every day, especially with an interlaboratory program that offers an option to receive instant interlaboratory feedback on demand.

One Interlaboratory Program, Two Valuable Options

Bio-Rad is pleased to offer laboratories that use the Unity data management software system the ability to receive on-demand InstantQC™ reports in addition to standard monthly Unity interlaboratory reports. This allows laboratories to take advantage of the best of two worlds.

InstantQC permits you to compare your control results to other laboratories any time. It is particularly useful for troubleshooting problems with test system performance because of the rapid report turnaround times.

In contrast, submission for monthly Unity is required once per month to ensure that peer group sizes are maximized for regular, periodic review of your test systems. Monthly Unity reports are more comprehensive than InstantQC reports. Both report types are available on the QCNet website for your convenience.


"To compare our data with a substantial peer group ensures that we are turning out reliable patient data."
— Laboratory Supervisor, School of Medicine
"The reports are clean and easy to read and understand. For each test, Unity Reports for our lab show a summary of our data, our instrument group, and our method group—reports are simple."
— Clinical Chemist, Hospital Laboratory
"The documentation of Bio-Rad Controls using the Unity QC Program has been well accepted by CAP inspectors. Worry free QC."
— Laboratory Director, Health Center

"Laboratories are encouraged to actively participate in interlaboratory QC programs..."
