Reproducerbarhed<br />
Reproducerbarheden hos <strong>BD</strong> ProbeTec <strong>ET</strong> <strong>LP</strong> analysen blev vurderet ved tre laboratorier ved at teste et panel<br />
bestående af 24 prøver, der blev spiket i PBS/BSA Panelet omfattede 12 prøver, der var negative for L <strong>pneumophila</strong>;<br />
tre lave (300 CFU/reaktion) og tre høje (500 CFU/reaktion) positive prøver af L <strong>pneumophila</strong>; og tre lave (hhv 30<br />
elementærlegemer (Elementary Bodies, EB)/reaktion, 300 CFU/reaktion, 900 celler/reaktion) og tre høje (hhv 50<br />
EB/reaktion, 500 CFU/reaktion, 1500 celler/reaktion) positive prøver hver indeholdende Chlamydophila pneumoniae<br />
(CP), L <strong>pneumophila</strong> (<strong>LP</strong>), og Mycoplasma pneumoniae (MP) En operatør pr sted testede panelerne en gang om<br />
