Radioimmunoassay for clindamycin.

T J Gilbertson, R P Stryd

    Clinical Chemistry
    |June 1, 1976
    PubMed
    Summary

    A new radioimmunoassay accurately measures clindamycin in serum, outperforming the microbiological assay. This method is unaffected by other antibiotics and offers high sensitivity for drug monitoring.

    Area of Science:

    • Pharmacology
    • Analytical Chemistry
    • Clinical Diagnostics

    Background:

    • Accurate measurement of clindamycin levels is crucial for effective therapeutic drug monitoring.
    • Existing microbiological assays for clindamycin may be affected by metabolites and other antibiotics.

    Purpose of the Study:

    • To develop and validate a radioimmunoassay for quantifying clindamycin in serum extracts.
    • To compare the accuracy and specificity of the radioimmunoassay against the microbiological assay.

    Main Methods:

    • Development of a radioimmunoassay utilizing serum extracts.
    • Validation of the assay's sensitivity, specificity, and accuracy.
    • Comparison with a standard microbiological assay.

    Main Results:

    • The radioimmunoassay demonstrated higher accuracy compared to the microbiological assay.
    • The assay showed minimal cross-reactivity with the clindamycin metabolite, N-demethylclindamycin.
    • The method is not influenced by the presence of other antibiotics.

    Conclusions:

    • The developed radioimmunoassay provides a more accurate method for clindamycin measurement in serum.
    • This assay offers improved specificity and can be further enhanced for greater sensitivity.
