A comparison of commercial kits for the measurement of lipoprotein(a).

Five commercial kits for the assay of lipoprotein(a) were investigated and two of these, the Immuno Enzyquick and Biopool TintElize, both enzyme-linked immunoassays, were studied in detail. Whilst there was a strong correlation between the results obtained using the two methods there was a significant difference between the absolute values. In view of its higher precision at low levels and robust performance, the Enzyquick kit (Immuno Ltd) was selected for use in this laboratory.
