The latex slide test is intended to be used as an aid in evaluation of the amount of injury to body tissues. ## Device Story RaPET® CRP is an in vitro diagnostic latex agglutination slide test. Input: human serum sample. Principle: latex beads coated with monospecific anti-human CRP (goat) antibodies; agglutination occurs in the presence of CRP. Output: visual qualitative or semi-quantitative assessment of CRP levels. Used in clinical laboratory settings by trained personnel. Results assist clinicians in evaluating tissue injury. Benefits: provides rapid, actionable data for clinical decision-making regarding inflammatory states. ## Clinical Evidence Bench testing only. Method comparison performed against Pulse's C-Reactive Protein Test (n not specified). Correlation coefficient 0.964; regression equation Y=0.93X + 0.36. Precision, sensitivity, specificity, and interference studies reported as acceptable. ## Technological Characteristics Latex agglutination slide test. Components: CRP latex reagent, CRP positive control, negative control, glycine/saline buffer. Sensing principle: antigen-antibody agglutination reaction using goat anti-human CRP coated latex beads. Manual visual interpretation. No electronic components or software. ## Regulatory Identification A C-reactive protein immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the C-reactive protein in serum and other body fluids. Measurement of C-reactive protein aids in evaluation of the amount of injury to body tissues. ## Predicate Devices - Pulse's C-Reactive Protein Test ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

(210) 222-2108 Fax (210) 227-6367 Prepared By Kirk Johnson November 14, 1997 ## Product Name Trade Name: RaPET® CRP Common Name: C-Reactive Test Classification Number: 82DCN ## Description of Device The device test kit is comprised of CRP Latex Reagent, CRP Positive Control, Negative Control and Glycine/Saline Buffer for performing semi-quantitative testing. ## Intended Use of Device RaPET® CRP is intended for the qualitative and semi-quantitative detection of C-Reactive Protein in human serum. The latex slide test is intended to be used as an aid in evaluation of the amount of injury to body tissues. ## Comparison of Devices Both RF latex methods employ latex beads coated with monospecific anti-human CRP (goat) which agglutinate in the presence of C-reactive protein serum. ## Performance Data Substantial equivalency was demonstrated by method comparison to Pulse's C-Reactive Protein Test. Correlation was performed between the two test kits with a correlation coefficient of 0.964 and a regression equation of $Y=0.93X + 0.36$. In addition, precision, sensitivity, specificity, and interference studies were performed on RaPET® CRP. Results of these tests were found to be acceptable. - 18 - STA BORATORY, INC. 2930 East Houston Street San Antonio, Texas 78202 (210) 222-2108 1-800-531-5535 FAX (210) 227-6367 {1} DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service Food and Drug Administration 2098 Gaither Road Rockville MD 20850 FEB 18 1998 Kirk Johnson Quality Assurance Manager Stanbio Laboratory, Inc. 2930 East Houston Street San Antonio, TX 78202 Re: K974429 Trade Name: RaPET® CRP Regulatory Class: II Product Code: DCN 82 Dated: November 19, 1997 Received: November 24, 1997 Dear Mr. Johnson: We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class-III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations. {2} Page 2 Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization. To determine if it does, you should contact the Centers for Disease Control and Prevention (CDC) at (770)488-7655. This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for *in vitro* diagnostic devices), please contact the Office of Compliance at (301) 594-4588.
