Reliable Proficiency Testing for Food Safety Laboratories

 Need PTs on your schedule—not the calendar’s? Express PTs provide full-blind proficiency testing with flexible ordering and quick turnaround.

Why choose Express PTs?

• Full-blind PT integrity
• Fast shipping and accelerated turnaround
• 45-day evaluation window
• Direct support from S&A Scientific
   

Express PTs are ideal for method verification, staff competency assessments, corrective actions, and unexpected regulatory deadlines—without waiting for scheduled PT cycles.

Internal PTs are designed to strengthen staff competency and optimize laboratory methods without the pressure of accreditation requirements. These practice materials include known assigned values, making them ideal for hands-on learning and internal performance checks.

Ideal for:

• Staff training and onboarding
• Method optimization and troubleshooting
• Internal quality checks and audits
  Why choose Internal PTs?
• Produced separately from official study PTs
• Provided with known assigned values for immediate learning
• Strictly for education and quality improvement
   

Note: Internal PTs do not meet state, federal, or accreditation PT requirements—they are purely for skill-building and internal evaluation.
