Hi Leukocyte esterase
is positive when there are pus cells in the urine tested (usually >5/LPF) with occasional bacteria.
It does not surely indicate STD but there is a bit of bacterial infection and if hygeine is maintained then probably it will come out to be negative on the next testing, provided you are not suffering from the following symptoms :
burning, fever with chills
, frequent urination
, lower abdominal pain
. If these symptoms are present then you need to start an antibiotic
