## Indications for Use

This product permits the quantitative in vitro diagnostic determination of Complement 4 in serum and plasma on the ILab Clinical Chemistry System by turbidimetric immunoassay method. C4 is one of a group of serum proteins which destroy infectious agents. Measurement of this protein aids in the diagnosis of immunologic disorders, especially those associated with deficiencies of C4.

## Device Story

Turbidimetric immunoassay for quantitative C4 determination in serum/plasma; performed on ILab Clinical Chemistry System. Input: patient serum/plasma samples. Principle: antigen-antibody reaction causing turbidity proportional to C4 concentration. Output: quantitative C4 levels. Used in clinical laboratory settings by trained laboratory personnel. Results assist clinicians in diagnosing immunologic disorders and C4 deficiencies.

## Clinical Evidence

Method comparison study; 38 serum samples; compared quantex C4 on ILab system vs. IL Test™ C4 on Monarch system. Correlation coefficient (r) = 0.9791.

## Technological Characteristics

Turbidimetric immunoassay; reagents include anti-human C4 and buffer. Designed for use on ILab Clinical Chemistry System. Quantitative measurement of serum proteins.

## Regulatory Identification

A complement components immunological test system is a device that consists of the reagents used to measure by immunochemical techniques complement components C1q , C1r , C1s , C2 , C3 , C4 , C5 , C6 , C7 , C8 , and C9 , in serum, other body fluids, and tissues. Complement is a group of serum proteins which destroy infectious agents. Measurements of these proteins aids in the diagnosis of immunologic disorders, especially those associated with deficiencies of complement components.

**Summary Prepared:**

May 29, 1996

**Name of the device:**

quantex C4:
8 x 6 mL anti-human C4 P/N 3000-22137
2 x 100 mL Buffer P/N 3000-22130

**Classification name(s):**

866.5240 Complement components immunological test systems Class II

**Identification of predicate device(s):**

IL Test™ C4 #K920010/B

**Description of the device/intended use(s):**

This product permits the quantitative *in vitro* diagnostic determination of Complement 4 in serum and plasma on the ILab Clinical Chemistry System by turbidimetric immunoassay method. C4 is one of a group of serum proteins which destroy infectious agents. Measurement of this protein aids in the diagnosis of immunologic disorders, especially those associated with deficiencies of C4.

**Statement of how the Technological Characteristics of the Device compare to the Predicate device:**

Biokit’s quantex C4 is substantially equivalent in performance, intended use, safety and effectiveness to the predicate, IL Test™ C4 -- 510(k) #K920010/B.

**Summary of Performance Data:**

A comparative performance study was performed with IL Test™ C4 on a Monarch Clinical Chemistry System and Biokit’s quantex C4 on an ILab Clinical Chemistry System. Method comparison studies evaluated C4 levels of thirty-eight serum samples on the respective instruments. The correlation $(r)$ in these studies was 0.9791.
