The Risks of Buying Low Quality Equipment
Data Integrity in Clinical Trials
Why Standardization, Calibration, and Equipment Accuracy Control Study Outcomes
In this article, we want to highlight our concerns about the use of low-quality and unproven equipment in clinical trials and research; because if you’re involved in trials or studies, the differences matter more than they might seem. We value procurement partners, but decision-makers deserve clear facts that protect study outcomes.
Why We’re Concerned
We continue to see procurement vendors sourcing alternative Illuminator Cabinets, bulbs, and other products marketed as equal to ours. On the surface, these products can look similar and claim to meet the same specs, but the underlying realities introduce significant trial liabilities:
- Most vendors do not manufacture, calibrate, or verify calibration.
- Substitutions may occur without disclosure to trial sponsors or CROs.
- Vendors may not fully understand the technical variations between genuine and substitute testing equipment.
Consistency & Calibration are Critical
Working with human subjects introduces many uncontrollable variables. Managing test repeatability—such as Best Corrected Visual Acuity (BCVA) and Low Contrast Visual Acuity (LCVA)—across patients and sites is essential. Fortunately, it’s also the easiest variable to control with high-quality equipment:
- Every 2425 LED flat panel cabinet is precisely calibrated to meet posted luminance values.
- Traditional fluorescent 2425 cabinets are built in small, calibrated production lots.
- Our 2425 ETDRS® Illuminator Cabinet™ has evolved through four generations, always holding the same high standards to protect data integrity.
Nobody does what we do.
