Was Xpert testing performed at point of care?
(POCT is diagnostic testing that will result in a
clear and actionable management decision (e.g.
start of treatment, referral, initiation of confirmatory
test) within the same clinical encounter (e.g. same
day). POCT should be mentioned in the study as
it is unlikely if testing takes place in a central
level laboratory.

VIII. Results
Did the study report % contaminated cultures?
(Enter percentage contaminated cultures, if
provided): # of contaminated cultures/Total # cultures performed = %
1 – Yes ‐> % contaminated cultures: 2 – No
Did the study report the number of uninterpretable
results for Xpert for tuberculosis detection? (invalid, error, no result) The uninterpretable rate for detection of PTB is the
number of tests classified as “invalid,” “error,” or “no result”
divided by the total number of Xpert tests performed.
1 – Yes ‐> # Uninterpretable results: Denominator is total number of Xpert tests performed
(Add total from Table 1 plus # of uninterpretable results): 2 – No
Did the study report the number of indeterminate results for
Xpert for rifampicin resistance detection? The indeterminate rate for detection of rifampicin resistance
was the number of tests classified as “MTB detected; Rif
resistance INDETERMINATE” divided by the total number
of Xpert‐MTB positive results
1 – Yes ‐># Indeterminate results: (Enter 0 indeterminate results if the total number in
Table 6 = the number of TPs in Table1) Denominator is total number of Xpert tests performed
(Total Xpert positive results from Table 1 first row): 2 – No
Did the study report any Xpert rifampicin resistant positive
results in culture negative specimens?
1 – Yes ‐> Number reported: 2 – No
Did the study report nontuberculous mycobacteria (NTM)?
Record number NTM over the number of cultures performed

results among NTMs
#Xpert positive tests among total number NTMs: 9 – Unknown/NR
