## Indications for Use

qUAntify® Control and qUAntify® Plus Control are intended for use as an assayed quality control to monitor the precision of urinalysis test procedures for the analytes listed in the package insert. For Prescription Use Only

## Device Story

qUAntify® Control and qUAntify® Plus Control are liquid matrix quality control solutions used in clinical laboratories to monitor the precision of urinalysis test procedures. The controls contain human erythrocytes, leukocytes (in Plus version only), animal-derived constituents, chemicals, and preservatives. They are provided in two levels. Laboratory personnel use these controls to verify the performance of urinalysis assays by comparing observed results against assigned values provided in the package insert. This process ensures the reliability of patient test results for various analytes, including glucose, hCG, protein, and specific gravity, thereby supporting accurate clinical decision-making.

## Clinical Evidence

No clinical data. Stability studies performed to determine open vial stability (31 days at 2-8°C or 18-25°C) and shelf life (two years at 2-8°C).

## Technological Characteristics

Liquid matrix solution containing human erythrocytes, leukocytes, animal-derived constituents, chemicals, and preservatives (<0.1%). Analytes include albumin, creatinine, bilirubin, blood, glucose, hCG, ketones, leukocytes, nitrite, protein, pH, urobilinogen, and specific gravity. Storage at 2°C to 8°C. No software or electronic components.

## Regulatory Identification

A quality control material (assayed and unassayed) for clinical chemistry is a device intended for medical purposes for use in a test system to estimate test precision and to detect systematic analytical deviations that may arise from reagent or analytical instrument variation. A quality control material (assayed and unassayed) may be used for proficiency testing in interlaboratory surveys. This generic type of device includes controls (assayed and unassayed) for blood gases, electrolytes, enzymes, multianalytes (all kinds), single (specified) analytes, or urinalysis controls.

## Predicate Devices

- Liquichek™ Urinalysis Control ([K031231](/device/K031231.md))
