POC test for Pleural TB
I know this post does not perfectly fit under this category but I was hoping for the experience of people who are working in TB around the globe.
Consider the development of a rapid point-of care (POC) test for pleural TB on pleural fluid.
If the test was highly sensitive it could be used at a peripheral health clinic and if negative the patient could be referred on to a higher level of care for further workup. However do you consider a test like this being a feasible test in a health clinic (thoracentesis required)?
One could also consider such a rapid POC test in a district hospital. However, given that biochemical analysis and cell count/differential would likely be available at that level of care, the additive value of the test in respect to sensitivity might be limited. Do you think a very specific test would be helpful in that context to avoid unnecessary treatment (possibly while awaiting culture or biopsy results)?
Thank you for your opinion.
