The ACE Direct Total Iron-Binding Capacity (TIBC) Reagent is intended for the quantitative determination of total iron-binding capacity in serum using the ACE Alera Clinical Chemistry System. Iron-binding capacity measurements are used in the diagnosis and treatment of anemia. This test is intended for use in clinical laboratories and physician office laboratories. For in vitro diagnostic use only. The ACE Total Iron Reagent is intended for the quantitative determination of iron in serum using the ACE Alera Clinical Chemistry System. Iron (non-heme) measurements are used in the diagnosis and treatment of diseases such as iron deficiency anemia, hemochromatosis (a disease associated with widespread deposit in the tissues of two iron-containing pigments, hemosiderin and hemofuscin, and characterized by pigmentation of the skin), and chronic renal disease. This test is intended for use in clinical laboratories and 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 Alera 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 and physician office laboratories. For in vitro diagnostic use only.

In the ACE Direct Total Iron-Binding Capacity (TIBC) Reagent assay, Direct TIBC Color Reagent, an acidic buffer containing an iron-binding dye and ferric chloride, is added to the serum sample. The low pH of Direct TIBC Color Reagent releases iron from transferrin. The iron then forms a colored complex with the dye. The colored complex at the end of the first step represents both the serum iron and excess iron already present in Direct TIBC Color Reagent. Direct TIBC Buffer, a neutral buffer, is then added, shifting the pH and resulting in a large increase in the affinity of transferrin for iron. The serum transferrin rapidly binds the iron by abstracting it from the dye-iron complex. The observed decrease in absorbance of the colored dye-iron complex is directly proportional to the total iron-binding capacity of the serum sample. The absorbance is measured at 647 nm. In the ACE Total Iron Reagent assay, transferrin-bound iron in serum is released at an acidic pH and reduced from ferric to ferrous ions. These ions react with ferrozine to form a violet colored complex, which is measured bichromatically at 554 nm/692 nm. The intensity of color produced is directly proportional to the serum iron concentration. 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 S-Test Lactate Dehydrogenase Reagent is intended for the quantitative determination of lactate dehydrogenase activity in serum using the S40 Clinical Analyzer. 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.

The S-Test Lactate Dehydrogenase (LD) reagent cartridge, used with the S40 Clinical Analyzer, is intended for the quantitative in vitro diagnostic determination of LD activity in serum based on a photometric test measuring the rate of conversion of NADH from NAD in an enzyme assay. It is composed of a bi-reagent cartridge, and is intended for use in clinical laboratories or physician office laboratories.

The Piccolo Lactate Dehydrogenase Test System (presently contained on the Piccolo Basic Metabolic Panel Plus Reagent Disc) used with the Piccolo Point-of-Care Chemistry Analyzer is intended to be used for the in vitro quantitative determination of lactate dehydrogenase activity in heparinized plasma or serum in a clinical laboratory setting or point-of-care location. Lactate dehydrogenase measurements are used in the diagnosis and treatment of liver diseases such as acute viral hepatitis and cirrhosis; cardiac diseases such as myocardial infarction; malignant diseases; and tissue alterations of the heart, kidney, liver, and muscle.

The Piccolo Basic Metabolic Panel Plus Reagent Disc (which contains the Piccolo Lactate Dehydrogenase Test System) is designed for heparinized plasma and serum, only. The disc meters the required quantity of sample and diluent, mixes the sample with diluent, and delivers the mixture to the reaction cuvettes along the disc perimeter. The diluted samples mixes with the reagent beads, initiating the chemical reactions that are then monitored by the analyzer. Alternately, the disc may also be used with serum.

For the quantitative determination of Lactate Dehydrogenase in serum. For IN VITRO diagnostic use. Elevated levels of lactate dehydrogenase are clinically significant and can be found in disease states which result in cell damage. Myocardial infarcts, liver disease, megaloblastic anemias, renal disease, progressive muscular dystrophy and some malignancies all produce elevated lactate dehydrogenase values in serum (1).

Lactate Dehydrogenase-SL Assay

This product is to be used in a diagnostic laboratory setting, by qualified laboratory technologists, for the quantitative determination of Lactate dehydrogenase in serum or leomonogram in the for in vitro diagnostic use only. The determination of Lactate dehydrogenase in serum is most commonly performed for the diagnosis and treatment of myocardial infarctions. LD elevations are also observed in liver disease, pernicious anemia, some cases of renal disease, and in cases of skeletal muscle trauma.
