Intended Use

Immunoturbidimetric assay for the in vitro determination of alpha-1-antitrypsin in human serum and plasma. This product is suitable for use on RX series instruments which includes the RX daytona and the RX imola.

Clinical Significance

Measurement of alpha-1-antitrypsin levels in serum and plasma aid in the diagnosis of several conditions including juvenile and adult cirrhosis of the liver. In addition, alpha-1-antitrypsin deficiency has been associated with pulmonary emphysema.


Sample is diluted and reacted with a buffer containing antibody specific for alpha-1-antitrypsin. The formation of the antibody-antigen complex during the reaction results in an increase in turbidity, the extent of which is measured as the amount of light absorbed at 340 nm. By constructing a standard curve from the absorbance of standards, alpha-1-antitrypsin concentration of sample can be determined.

Available Applications

RX series instruments, including:

RX daytona

RX imola
