Intended Use
The ACE Axcel Clinical Chemistry System is an automated, discrete, bench-top, random access analyzer that is intended for in vitro diagnostic use in the quantitative determination of constituents in blood and other fluids. The ACE Alkaline Phosphatase Reagent is intended for the quantitative determination of alkaline phosphatase activity in serum using the ACE Axcel Clinical Chemistry System. Measurements of alkaline phosphatase are used in the diagnosis and treatment of liver, bone, parathyroid, and intestinal diseases. This test is intended for use in clinical laboratories or physician office laboratories. For in vitro diagnostic use only. The ACE Amylase Reagent is intended for the quantitative determination of a-amylase activity in serum using the ACE Axcel Clinical Chemistry System. Amylase measurements are used primarily for the diagnosis and treatment of pancreatitis (inflammation of the pancreas). This test is intended for use in clinical laboratories or physician office laboratories. For in vitro diagnostic use only. The ACE LDH-L Reagent is intended for the quantitative determination of lactate dehydrogenase activity in serum using the ACE Axcel Clinical Chemistry System. Lactate dehydrogenase measurements are used in the diagnosis and treatment of liver diseases such as acute viral hepatitis, cirrhosis, and metastatic carcinoma of the liver, cardiac diseases such as myocardial infarction and tumors of the lung or kidneys. This test is intended for use in clinical laboratories or physician office laboratories. For in vitro diagnostic use only.
Device Description
The ACE Axcel Clinical Chemistry System consists of two major components, the chemistry instrument and an integrated Panel PC. The instrument accepts the physical patient samples, performs the appropriate optical or potentiometric measurements on those samples and communicates that data to an integral Panel PC. The Panel PC uses keyboard or touch screen input to manually enter a variety of data, control and accept data from the instrument, manage and maintain system information and generate reports relative to patient status and instrument performance. The Panel PC also allows remote download of patient requisitions and upload of patient results via a standard interface. In the ACE Alkaline Phosphatase Reagent assay, alkaline phosphatase in serum catalyzes the hydrolysis of colorless p-nitrophenyl phosphate to p-nitrophenol and inorganic phosphate. In an alkaline solution (pH 10.5), p-nitrophenol is in the phenoxide form and has a strong absorbance at 408 nm. The rate of increase in absorbance, monitored bichromatically at 408 nm/486 nm, is directly proportional to the alkaline phosphatase activity in the sample. In the ACE AST Reagent assay, a-amylase hydrolyzes the 2-chloro-p- nitrophenyl-a-D-maltotrioside substrate to release 2-chloro-p- nitrophenol and form 2-chloro-p- nitrophenyl-a-D-maltoside, maltotriose and glucose. The rate of increase in absorbance, monitored bichromatically at 408 nm/ 647 nm, is directly proportional to the a- amylase activity in the sample. In the ACE LDH-L Reagent assay, lactate dehydrogenase catalyzes the conversion of L-lactate to pyruvate. Nicotinamide adenine dinucleotide (NAD+) acts as an acceptor for the hydrogen ions released from the L- lactate and is converted to reduced nicotinamide adenine dinucleotide (NADH). NADH absorbs strongly at 340 nm whereas NAD+ does not. Therefore, the rate of conversion of NAD+ to NADH can be determined by monitoring the increase in absorbance bichromatically at 340 nm/647 nm. This rate of conversion from NAD+ to NADH is directly proportional to the lactate dehydrogenase activity in the sample.

The instrument has a capacity of 40 reagent containers on board. A reagent cooling system maintains the reagents at 12°C during instrument operation. Reagent containers are identified by computer coded labels to simplify system operation. All reagents in the system must include an identification label on the container.
Sample and reagent sensing notify the operator of a depleted condition during operation. The system performs analysis at a reaction temperature of 37°C. An electrolyte subsystem capable of measuring sodium, potassium and chloride concentrations is included. Primary draw tubes may be introduced one at a time into the system for closed tube sampling. Positive tube identification can be achieved with an optional barcode scanner. An aliquot volume sufficient for all tests ordered is transferred and stored and the closed tube is returned to the user. Sample cups are introduced to the system one at a time or by sample ring segment. Disposable cuvettes are loaded in bulk and then automatically injected as needed by a cuvette hopper system. The ACE Axcel clinical chemistry optical system is capable of monitoring a maximum of 48 cuvettes at one time. The absorbance optical system is capable of absorbance measurements in a linear range of 0.0 to 2.0 absorbance units (at 0.67 cm pathlength). Sixteen wavelengths are measured simultaneously using a photodiode array. The ACE Alkaline Phosphatase Reagent is composed of two reagent bottles (Buffer and Substrate Reagent).
