Indications for Use

The CARESIDE Triglyceride cartridge is intended for in vitro diagnostic use in conjunction with the CARESIDE Analyzer to quantitatively measure the concentration of triglycerides in anti-coagulated whole blood, plasma or serum. This product is indicated for use in the diagnosis and treatment of patients with primary or secondary hyperlipidemias. Hyperlipidemias may result from liver obstruction, diseases involving lipid metabolism, or various endocrine disorders. Triglyceride results are used together by the CARESIDE Analyzer with total cholesterol and HDL-cholesterol results to calculate LDL-cholesterol levels.

Device Story

CARESIDE Triglyceride cartridge is a single-use, disposable in vitro diagnostic test used with the CARESIDE Analyzer. User introduces anticoagulated whole blood, serum, or plasma into cartridge sample well. Analyzer automatically separates blood cells via centrifugation, meters plasma/serum, and dispenses it onto a multi-layer reagent film. Triglyceride concentration is measured via lipase hydrolysis coupled to a glycerol kinase-based reflectance system. Photodiodes measure reflectance of light emitted by LEDs at 570 nm. Instrument uses lot-specific standard curve to calculate concentration. Results are used by clinicians to diagnose/treat hyperlipidemias and calculate LDL-cholesterol levels. Benefits include rapid, point-of-care quantitative measurement without manual sample dilution or pre-separation.

Clinical Evidence

Bench testing only. Method comparison against BM/Hitachi 902 yielded r=0.98, slope 0.98, intercept 2.92 mg/dL. Precision (total CV) 3.4% at 146 mg/dL. Mean recovery 99%. Interference testing showed no significant interference from ascorbic acid (10 mg/dL), bilirubin (10 mg/dL), or hemoglobin (500 mg/dL).

Technological Characteristics

Multi-layer reagent film in plastic cartridge. Sensing principle: lipase hydrolysis coupled to glycerol kinase-based reflectance detection. Light source: LED (570 nm). Connectivity: barcode-scanned calibration. Operational temp: 37°C. Sample volume: 8.5 μL (metered).

Indications for Use

Indicated for diagnosis and treatment of patients with primary or secondary hyperlipidemias (e.g., liver obstruction, lipid metabolism diseases, endocrine disorders). Used with CARESIDE Analyzer to measure triglycerides in anti-coagulated whole blood, plasma, or serum.

Regulatory Classification

#### IV. Device Description

CARESIDE Trighceride cartridges are used with the CARESIDE Analyzer to measure triglyceride concentration in anti-coagulated whole blood, plasma or serum specimens. The CARESIDE Triglyceride cartridge, a single use disposable in vitro diagnostic test cartridge, aids in specimen separation and delivers a measured volume of plasma or serum to a dry film to initiate the measurement of triglyceride concentration. The patented film cartridge contains all reagents necessary to measure triglyceride concentration.

#### A. Explanation of Device Function

Each CARESIDE Triglyceride cartridge consists of a triglyceride-specific multi-layer reagent film mounted in a plastic base with a hinged lid. The user introduces the anticoagulated whole blood, serum, or plasma specimen into the cartridge Sample Well, closes the lid and inserts the cartridge into the CARESIDE Analyzer.

Once loaded, the CARESIDE Analyzer scans the cartridge barcode, brings the cartridge and the contained specimen to 37℃, and spins the cartridge to move the sample from the sample deposition well into the cartridge channels and chambers. As the cartridge continues to spin, the blood cells are separated from the plasma/serum and the cells accumulate in the separation well. Approximately 8.5 microliters of plasma (or serum, as applicable) remain in the metering passage. Any excess sample flows into an overflow well.

The plasma (or serum, as applicable) is automatically dispensed onto the multi-layer The triglyceride-containing specimen is distributed uniformly by the reagent film. spreading layer. The sample then passes through a reflection layer and into the reaction layer. Finally, the reaction mixture is pulled through the reaction layer by a suction layer where the NTB chromogen is converted into a purple formazan dye.

As the cartridge spins, a photodiode measures film reflectance of light emitted from a wavelength-specific light emitting diode (LED) at a lixed time. The instrument uses the reflectance measurements and the lot-specific standard curve to calculate triglyceride concentration.

Test Reaction Sequence:

LPL > Glycerol + Fatty Acid Triglycerides -

GK Ms++> G-3-P + ADP Glycerol + ATP =

G-3-P + NAD+ -- -- 3-10->DHAP + NADH

NTB + NADH -- 2:iuphorsse > Formazan dye + NAD*

As the cartridges spin, photodiodes measure reflectance of light emitted by wavelengthspecific light emitting diodes (LEDs) at a fixed time. The instrument uses the reflectance measurements and the lot-specific standard curve to calculate triglyceride concentration.

#### B. Test Summary

Triglycerides, consisting of fatty acids in ester linkages with glycerol, are the major form of fat found in the body. The primary function of triglyceride is to store energy.

Elevated triglycerides in patients reflect primary disorders of lipid metabolism or hyperlipoproteinemia secondary to known diseases including diabetes mellitus, nephrosis, biliary obstruction, pancreatitis and metabolic disorders associated with endocrine disturbances. Elevated levels of triglycerides has been identified as a risk factor related to atherosclerotic disease leading to coronary heart disease. Plasma levels of triglycerides can vary independently of lipoprotein levels; therefore evaluation of hyperlipidemias should include determinations of triglycerides.
