Intended Use

For the quantitative in vitro determination of Phenobarbital in human serum. This product is suitable for use on the RX series instruments which includes the RX daytona and RX imola.

Clinical Signifiance

This phenobarbital test system is a device intended to measure phenobarbital, an antiepileptic and sedative-hypnotic drug, in human serum. Measurements obtained by this device are used in the diagnosis and treatment of phenobarbital use or overdose and in monitoring levels of phenobarbital to ensure appropriate therapy.


Randox Phenobarbital assay is a latex-enhanced immunoturbidimetric assay. It is based on the principle of measuring changes in scattered light. The latex particles are coated with phenobarbital, which in the presence of phenobarbital antibody solution, rapidly agglutinate.

When a sample containing phenobarbital is introduced, the agglutination reaction is partially inhibited, slowing down the agglutination process. The rate of agglutination is inversely dependent upon the concentration of phenobarbital in the sample. By monitoring the change in scattered light, as a change in absorbance, a concentration curve can be obtained. The actual change in absorbance is inversely proportional to the concentration of phenobarbital in the sample.

This assay uses an end point method and multipoint calibration.

Available Applications

RX series instruments, including:

RX daytona

RX imola
