VITROS® Automation Solutions is a configurable, scalable laboratory automation system (LAS) designed to streamline pre and post analytical processes in the clinical laboratory. VITROS® Automation Solutions is comprised of personal computer (PC) Kit(s) (including software and hardware), sample conveyors with turns, parallel and perpendicular bypasses, storage module, single-tube entry, rack entry and exit, centrifuge, de-capper modules and clinical analyzers. In the basic configuration, patient sample tubes are loaded onto the automation track to be centrifuged, de-capped, and sorted for further processing on clinical analyzers such as the VITROS® Systems. Additional modules may be added to enable aliquot capability, sample capping, and refrigerated storage. Parallel and perpendicular bypasses are extensions of the automation track that link with an analyzer's existing laboratory automation system (LAS) interface. These bypasses support on-track metering at the analyzer based on point-in-space pipetting technology and robotic interface module (RIM). With point in space pipetting, the automation performs the sample bar code read function, presents the sample identification to the connected analyzer, and then signals for direct sampling of the open tube by the connected analyzer at an aspiration point on the automation track. With robotic interface modules, the sample tube is transferred to the analyzer and the analyzer will read the bar code to identify the sample, aspirate sample from the tube and perform the test(s) requested and then return the tube to the LAS. VITROS® Automation Solutions allows the establishment of a connection with clinical analyzers such as VITROS® Systems to enable sample routing based on reagent and calibration status. The clinical analyzers, such as VITROS® Systems, will perform all functions with respect to result generation, including sample metering, assay processing and reporting for the assays. The VITROS® Systems are fully automated, computer controlled, clinical chemistry and immunodiagnostic analyzers intended for the in vitro determination of a variety of general chemistries, therapeutic drugs, drugs of abuse, proteins, infectious diseases, as well as cardiac, metabolic, thyroid, anemia, and oncology markers in biological fluids such as serum, plasma, urine and cerebral spinal fluid. The VITROS® Systems operate in conjunction with VITROS® Immunodiagnostic and Chemistry Products, reagents, calibrators and controls designed for use with the systems in the MicroSlide, MicroTip or MicroWell format. Representative assays (carbamazepine, gentamicin and total thyroxine) are used to demonstrate acceptable performance.

In the ACE γ-GT Reagent assay, γ-GT in serum or heparin plasma catalyzes the transfer of the γ-glutamyl group from L-γ-glutamyl-3-carboxy-4-nitroanilide to glycylglycine in the reagent. The product, 5-amino-2-nitrobenzoate, absorbs strongly at 408 nm. The rate of increase in absorbance, monitored bichromatically at 408 nm/486 nm, is directly proportional to the γ-GT activity in the sample. In the ACE Lipase Reagent Assay, lipase in serum or heparin plasma acts on a natural substrate, 1,2-diglyceride, to liberate 2-monoglyceride. This is hydrolyzed by monoglyceride lipase (a highly specific enzyme for monoglyceride) into glycerol and free fatty acid. Glycerol kinase acts on glycerol to form glycerol-3-phosphate, which is in turn acted on by glycerol-3-phosphate oxidase to generate hydrogen peroxide. Peroxidase converts the hydrogen peroxide, 4-Aminoantipyrine and TOOS (N-ethyl-N-(2-hydroxy-3-sulfopropyl)-m-toluidine) into a quinine dye. The rate of formation of the dye, determined bichromatically at an absorbance of 573 nm/692 nm, is proportional to the lipase activity in the sample. The ACE T4 Assay is a homogeneous enzyme immunoassay using ready-to-use liquid ACE T4 Reagent. The assay uses 8-anilino-1-naphthalene sulfonic acid (ANS) to dissociate thyroxine from the plasma binding proteins. Using specific antibodies to thyroxine, this assay is based on the competition of glucose-6-phosphate dehydrogenase (G6PD) labeled thyroxine and the dissociated thyroxine in the sample for a fixed amount of specific antibody binding sites. In the absence of thyroxine from the sample, the thyroxine labeled G6PD in the second reagent is bound by the specific antibody in the first reagent, inhibiting the enzyme's activity. The enzyme G6PD catalyzes the oxidation of glucose-6-phosphate (G6P) with nicotinamide adenine dinucleotide (NADT) to form 6-phosphogluconate and reduced nicotinamide adenine dinucleotide (NADH). NADH strongly absorbs at 340 nm whereas NAD does not. The rate of conversion, determined by measuring the increase in absorbance bichromatically at 340 nm/505 nm during a fixed time interval, is directly proportional to the amount of thyroxine in the sample. The concentration of thyroxine is determined automatically by the ACE Clinical Chemistry Systems using a logarithmic calibration curve established with calibrators, which are provided separately.

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. Prior to the ACE Hemoglobin A1c (HbA1c) Reagent assay, whole blood samples require a pretreatment step, which is done on-board the analyzer. The red blood cells in the sample are lysed by the Hemoglobin Denaturant and the hemoglobin chains are hydrolyzed. For determination of HbA1c, a latex agglutination inhibition assay is used. In the absence of HbA1c in the sample, the agglutinator (synthetic polymer containing the immunoreactive portion of HbA1c) in the HbA1c Agglutinator Reagent and the antibody-coated microparticles in the HbA1c Antibody Reagent will agglutinate. The presence of HbA1c in the sample competes for the antibody binding sites and inhibits agglutination. The increase in absorbance, monitored monochromatically at 592 nm, is inversely proportional to the HbA1c present in the sample. For the determination of total hemoglobin, all hemoglobin derivatives in the sample are converted to alkaline hematin. The reaction produces a green colored solution, which is measured bichromatically at 573 nm/692 nm. The intensity of color produced is directly proportional to the total hemoglobin concentration in the sample. The concentrations of both HbA1c and total hemoglobin are measured, the ratio is calculated and the result reported as percent HbA1c. The CEDIA T Uptake assay uses recombinant DNA technology to produce a unique homogeneous enzyme immunoassay system. The assay is based the bacterial enzyme β-galactosidase, which has been genetically engineered into two inactive fragments. These fragments spontaneously re-associate to form fully active enzyme which, in the assay format, cleaves a substrate, generating a color change that can be measured spectrophotometrically. In the assay, enzyme donor thyroxine conjugate binds directly to the unoccupied thyroxine-binding sites in the sample, preventing the spontaneous re-association of the enzyme fragments to form the active enzyme. Thus, thyroxine-binding proteins regulate the amount of β-galactosidase formed from the reassembly of the remaining donor and enzyme acceptor as monitored by the hydrolysis of the substrate o-nitrophenyl-β-galactopyranoside. The ACE T4 Assay is a homogeneous enzyme immunoassay using ready-to-use liquid ACE T4 Reagent. The assay uses 8-anilino-1-naphthalene sulfonic acid (ANS) to dissociate thyroxine from the plasma binding proteins. Using specific antibodies to thyroxine, this assay is based on the competition of glucose-6-phosphate dehydrogenase (G6PD) labeled thyroxine and the dissociated thyroxine in the sample for a fixed amount of specific antibody binding sites. In the absence of thyroxine from the sample, the thyroxine labeled G6PD in the second reagent is bound by the specific antibody in the first reagent, inhibiting the enzyme's activity. The enzyme G6PD catalyzes the oxidation of glucose-6-phosphate (G6P) with nicotinamide adenine dinucleotide (NAD+) to form 6-phosphogluconate and reduced nicotinamide adenine dinucleotide (NADH). NADH strongly absorbs at 340 nm whereas NAD+ does not. The rate of conversion, determined by measuring the increase in absorbance bichromatically at 340 nm/505 nm during a fixed time interval, is directly proportional to the amount of thyroxine in the sample. The concentration of thyroxine is determined automatically by the ACE Clinical Chemistry System using a logarithmic calibration curve established with calibrators, which are provided separately. In the Ferritin Assay, serum ferritin, in the presence of anti-ferritin conjugated latex micorparticles, and a buffer promoting aggregation, initiates an antigen-antibody reaction, resulting in the agglutination of the latex microparticles. The agglutination is detected turbidometrically by an absorbance change measured at a wavelength of 592 nm. The magnitude of the absorbance change is proportional to the ferritin concentration in the sample.

The GSP Neonatal Thyroxine (T4) kit is intended for the quantitative determination of human thyroxine (T4) in blood specimens dried on filter paper as an aid in screening newborns for congenital (neonatal) hypothyroidism using the GSP instrument.

The GSP Neonatal T4 assay is a solid phase time-resolved fluoroimmunoassay based on the competitive reaction between europium-labeled T4 and sample T4 for a limited amount of binding sites on T4 specific monoclonal antibodies (derived from mice). The use of 8-anilino-1-naphthalenesulfonic acid (ANS) and salicylate in the T4 Assay Buffer facilitates the release of T4 from the binding proteins. Thus the assay measures the total amount of T4 in the test specimen. A second antibody, directed against mouse IgG, is coated to the solid phase, and binds the IgG-thyroxine complex, giving convenient separation of the antibody-bound and free antigen. DELFIA Inducer dissociates europium ions from the labeled antibody into solution where they form highly fluorescent chelates with components of DELFIA Inducer. The fluorescence in each well is then measured. The fluorescence of each sample is inversely proportional to the concentration of T4 in the sample.
