Scope <strong>of</strong> Reviews<br />

Molecular Microbiology-nucleic acid amplification assays<br />

Method Validation<br />

Sensitivity (limit <strong>of</strong> detection)<br />

Data from a dilution series <strong>of</strong> a known concentration <strong>of</strong> the target<br />

(preferably whole organism) that is spiked into negative clinical samples<br />

for each matrix being validated.<br />

Perform 3 separate extractions <strong>of</strong> this dilution series and test in<br />

duplicate.<br />

The dilution series must encompass six dilutions including one below the<br />

limit <strong>of</strong> detection <strong>of</strong> the assay.<br />

If the LOD is determined to be >100 gene copies, linearity data must<br />

be provided.
