Nucleic acid amplification tests (NAATs) are frequently used in research and diagnostic testing, but the effect of freezing specimens on NAAT performance is not well characterized. This study evaluated the concordance of NAAT results between fresh and frozen specimens (fecal and rectal swabs) and found it to be very good to excellent. The results indicate that frozen fecal and rectal swab specimens may be used for NAAT testing in research when fresh specimens are not available.
