For qPCR\u2010based rapid tests, the sensitivity was 90% (95% CI: 88%\u201392%), and the specificity was 96% (95% CI: 95%\u201397%). For the LAMP\u2010based test, the sensitivity was 92% (95% CI: 84%\u201397%), and the specificity was 96% (95% CI: 94%\u201398%). When exploring study entry status, sample source, and test processing in the delivery room as sources of heterogeneity, we found no statistically significant differences between the subgroups analyzed (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.19,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.43, and\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.44).

For the LAMP\u2010based tests, the evidence is very uncertain regarding the acceptability of sensitivity (very low\u2010certainty evidence), but specificity is probably acceptable (moderate\u2010certainty evidence) for detecting GBS colonization in pregnant women.
