The Randox Laboratories Ltd. Lipoprotein (a) test kit is an in vitro diagnostic reagent for the quantitative determination of Lipoprotein (a) in serum and plasma. The method is an immunoturbidimetric assay in which agglutination occurs due to an antigenantibody reaction between Lp(a) in a sample and anti-Lp(a) antibody adsorbed to latex particles. The agglutination is detected as an absorbance change at 700nm proportional to the concentration of Lp(a) in the sample. Lp(a) determination is intended for use in conjunction with clinical evaluation, patient risk assessment and other lipid tests to evaluate disorders of lipid metabolism and lto assess coronary heart disease in specific populations.

I am sorry, but I cannot fulfill your request to describe the acceptance criteria and study proving device performance based on the provided text. The documents you supplied (a 510(k) clearance letter and an Indications for Use statement) do not contain the specific information needed to answer your questions.
Here's why:
- 510(k) Clearance Letter: This letter from the FDA confirms that the device (Randox Laboratories, Ltd. Lipoprotein (a) test kit) is "substantially equivalent" to legally marketed predicate devices. It allows the manufacturer to market the device but does not detail the specific performance studies, acceptance criteria, or ground truth methodologies that led to this determination. Substantial equivalence is based on comparing the new device to existing ones, not necessarily on new, extensive clinical trials for every clearance.
- Indications for Use: This section describes what the device measures (Lipoprotein (a) quantitatively) and its intended purpose (to evaluate lipid metabolism disorders and assess coronary heart disease risk). It outlines the intended use but provides no performance metrics or study details.
To answer your questions, I would need a different type of document, such as:
- A Clinical Study Report
- A Validation Study Report
- A Performance Characterization Document
- The 510(k) submission document itself (parts of it, specifically performance data sections)
Without such documents, I cannot extract the information required for the table and other detailed questions about acceptance criteria, sample sizes, expert qualifications, etc.

Dear Dr. Anderson:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). 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 (PMA), 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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

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 i additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its internet address "http://www.fda.gov/cdrh/dsma/dsmamain.html".
