Overview
In today's testing environment, specimen tampering is more sophisticated than ever. Traditional validity testing often relies on a limited number of markers — leaving gaps in detection.
Validity Plus® from Chemisys Laboratories was built to close those gaps. Our advanced specimen validity solution combines core integrity markers with expanded subversion detection to help providers confidently identify synthetic urine, adulteration, substitution, and dilution — before results are reported.
Many laboratories rely on only 4–6 basic validity tests (creatinine, pH, specific gravity, and one oxidant screen). Validity Plus® goes significantly further — combining essential specimen validity markers with expanded subversion analytics to evaluate a broad range of manipulation techniques.
Why it matters
Clinical value
Greater confidence in results
Reported results more accurately reflect true patient compliance and clinical conditions.
Reduced false reassurance
Expanded markers limit the risk that a compromised sample is reported as clean.
Stronger clinical decision-making
Providers make treatment and medication decisions on defensible laboratory data.
Program accountability
Supports early identification of tampering and protects program credibility.
