The APHL has recently released new guidelines for sputum specimen collection for TB diagnostic tests such as microscopy, culture and Xpert MTB/Rif. These guidelines include the purpose, materials, equipment, and steps which should be carried out effectively in order for patients to produce and submit quality specimens.
It is interesting to note that this document now includes the procedure for nebulized sputum induction, aside from the more common spontaneous collection. Remember that no amount of test or technology could offer the greatest accuracy and reliability unless specimens are collected in the best possible way.
Moreover, the contents of this guide can help laboratory and program managers in updating or developing current country diagnostics guidelines, whenever necessary. Below is the link:
