Diagnostic yield of early morning urine samples in the diagnosis of tuberculosis
| The first 10% of the full text of this article appears below. |
Sir,
Early morning urine (EMU) samples are sent in significant numbers from patients suspected of having tuberculosis (TB), despite evidence that the diagnostic yield is very low.1 We assessed the diagnostic yield of EMUs and calculated the associated workload, by retrospectively analysing data from our institution from January 2000 to June 2004.
