The SPQ™ Antibody Reagent Set for Lp(a) is designed for the quantitative determination of human lipoprotein(a) in mg/dL in human serum by immunoprecipitin analysis using a turbidimetric clinical analyzer. The measurement of Lp(a) is indicated for use in conjunction with clinical evaluation, patient risk assessment and other lipoprotein tests to evaluate disorders of lipid metabolism and to assess coronary heart disease (CHD) in male Caucasian populations. ## Device Story The SPQ™ III Antibody Reagent Set is an in vitro diagnostic kit for measuring human lipoprotein(a) (Lp(a)) in serum. It utilizes immunoprecipitin analysis on a turbidimetric clinical analyzer. The device functions by reacting patient serum with specific antibodies to form immune complexes, which are then measured via turbidity to quantify Lp(a) concentration in mg/dL. It is intended for use in clinical laboratory settings by trained personnel. The output provides a quantitative value used by clinicians alongside other lipoprotein tests and clinical evaluations to assess lipid metabolism disorders and coronary heart disease risk in male Caucasian populations. ## Clinical Evidence Bench testing with clinical samples was performed to compare the modified device against the predicate. Results demonstrated that the performance characteristics of the modified device are substantially equivalent to the predicate device. ## Technological Characteristics Immunological test kit for quantitative determination of Lp(a). Principle: Immunoprecipitin analysis using turbidimetric clinical analyzer. Modification includes additional antibody and reduced reaction time compared to the predicate. ## Regulatory Identification A low-density lipoprotein immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the low-density lipoprotein in serum and other body fluids. Measurement of low-density lipoprotein in serum may aid in the diagnosis of disorders of lipid (fat) metabolism and help to identify young persons at risk from cardiovascular diseases. ## Predicate Devices - SPQ™ II Antibody Reagent Set for Lipoprotein(a) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Trade Name: | Lipoprotein(a) SPQ™ III Antibody Reagent Set | | Common Name: | Lipoprotein(a) Immunological Test Kit | | Classification Name: | Lipoprotein(a), antigen, antiserum, control (82DFC) | | Device Classification | Class II | | Predicate Device: | SPQ™ II Antibody Reagent Set for Lipoprotein(a) | | Device Description: | Lipoprotein(a) Immunological Test Kit | | Intended Use: | FOR IN VITRO DIAGNOSTIC USE.
The SPQ™ Antibody Reagent Set for Lp(a) is designed for the
quantitative determination of human lipoprotein(a) in mg/dL in
human serum by immunoprecipitin analysis using a turbidimetric
clinical analyzer. The measurement of Lp(a) is indicated for use in
conjunction with clinical evaluation, patient risk assessment and
other lipoprotein tests to evaluate disorders of lipid metabolism
and to assess coronary heart disease (CHD) in male Caucasian
populations. | | Technological
Comparison: | The modified device has the same technological basis as the
predicate device. | | Labeling Comparison: | The labeling of the modified device is substantially equivalent to
that of the predicate device. Changes in labeling directly reflect the
device modification (additional antibody and reduced reaction time). | {1}------------------------------------------------ | Bench Testing
With Clinical Samples: | Bench testing with clinical samples demonstrated that the
performance characteristics of the modified device were
substantially equivalent to those of the predicate device. | |-----------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Conclusions from
Testing: | The modified device is substantially equivalent to the predicate

Worldwide Regulatory Affairs and Quality Systems Diasorin Inc. 9175 Guilford Road, Suite 100 Quarry Park Place Columbia, Maryland 21046 Re: K993669 > Trade Name: SPOTM III Test System Antibody Reagent Set for Lp(a) Regulatory Class: II Product Code: DFC Dated: October 29, 1999 Received: November 1, 1999 Dear Ms. Smith: 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 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). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include reguirements 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 OS 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. {3}------------------------------------------------ #### Page 2 Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization.
