The APOLOWAKO T-CHO is for the quantitative determination on the APOLOWAKO analyzer of total cholesterol in whole blood. The APOLOWAKO HDL-C is for the quantitative determination on the APOLOWAKO analyzer of HDL cholesterol in whole blood. The APOLOWAKO TG is for the quantitative determination on the APOLOWAKO analyzer of triglycerides in whole blood. In conjunction with the above values, the APOLOWAKO analyzer also calculates LDL cholesterol for triglyceride values up to 400 mg/dL and T-CHO/HDL-C ratio.
APOLOWAKO Analyzer is a discrete photometric chemistry analyzer for clinical use in both central laboratories and in point of care sites. The device is intended to duplicate manual analytical procedures by automatically performing various steps such as pipetting, mixing and measuring color intensity. This device is intended for use in conjunction with certain materials to measure a variety of analytes of clinical interest in whole blood samples.
The measurements of total cholesterol, HDL cholesterol, triglycerides, and LDL cholesterol (by calculation for triglyceride values up to 400 mg/dL) when used in conjunction with other biochemical markers and coronary risk factors, is useful in the prediction of CHD/CVD risk and the assessment of CHD/CVD severity.
The APOLOWAKO analyzer is a fully-integrated POC test system that can perform up to six analytical tests per individual sample. The analyzer automatically separates plasma from whole blood for testing. Once the plasma has been separated, it is transferred to a cell on a measurement disk where the chemical reactions take place. The analyzer uses liquid reagents which are packaged into kits. Each kit contains 2 reagent units. Each unit is composed of two enzyme color reagents and a lyophilized calibrator. All of the reagents have a reagent information tag applied to the back of each bottle which controls the reagent parameters and conditions such as, calibration, reagent quantity, shelf-life, and lot number. The instrument contains an automated liquid dispenser, temperature controlled reagent carrousel, analysis compartment, and sample holder. The instrument is designed to automatically and constantly monitor the reagents, dispensing system, measurement disk, and measurement process to ensure that no erroneous results are shown. The APOLOWAKO's lipid panel will include, total cholesterol, HDL cholesterol, LDL cholesterol (by calculation), and triglycerides in tubed venous whole blood. The test system is designed for professional use and consists of a small table top instrument (31 cm wide x 47.5 cm high x 56 cm deep, weight: 25 kg).
The provided text describes the Wako Diagnostics APOLOWAKO Lipid Panel and Analyzer, a point-of-care test system designed for the quantitative determination of total cholesterol, HDL cholesterol, and triglycerides in whole blood, with calculated LDL cholesterol. The device aims for substantial equivalence to the CHOLESTECH LDX system.
Here's an analysis of the acceptance criteria and study details:
1. A table of acceptance criteria and the reported device performance:
The document doesn't explicitly state "acceptance criteria" in a separate section. Instead, the performance characteristics (imprecision, linearity, interference) of the APOLOWAKO system are compared against or shown to be superior to those of the predicate device (Cholestech LDX) and demonstrate acceptable analytical performance. The substantial equivalence conclusion is based on comparable or better performance characteristics.

§ 862.1475 Lipoprotein test system.
(a)
Identification. A lipoprotein test system is a device intended to measure lipoprotein in serum and plasma. Lipoprotein measurements are used in the diagnosis and treatment of lipid disorders (such as diabetes mellitus), atherosclerosis, and various liver and renal diseases.(b)
Classification. Class I (general controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 862.9.
