I had gone there to do a test for my wife who is pregnent.the lady sitting in the counter did not give correct instructions that blood test needs to be done before glucose test. and she asked to drink glucose and come back after 2 hour which we did.when we came back she asked why i did not come first for blood test so because of this reason they cannot continue with glucose test.the reason is because blood test has to be done one before one empty stomach and one after 2 hours after drinking glucose on empty stomach.because of this we wasted one day and had to redo this the next day and my wife had already fasted the full morning since the previous night.when ever you go there please double check with them.
