Abstract
Advantages and disadvantages on the conventional semiquantitative CRP tests are discussed. Quantitative methods of determining serum CRP levels include radioimmuno assay, radio-electroimmuno-precipitation and laser immuno-nephelometry. Laser immunonephelometry has been most frequently applied in recent years. Some important problems related to laser immuno-nephelometry are discussed.
The authors recommend that polyethylene glycol is not to be added, that purified CRP standards are to be dissolved in absorbed human serum, and that inactivation of serum samples is preferable.
