First of all congratulations for clearing the medicals, in my case i took 3 BP readings as I have "White Coat Syndrome", the last reading was 140/83 and it was accepted by the doctor.
As per Abu Hassaan,
There is another test they are doing in case of BP reading slightly above normal /100 which called "Creatinine test" as far as I know to make sure that Kidney functions are okay, maybe they've made this test for you (don't remember if it is through blood or urine".
They told me that they have to make this Creatinine test to make sure of BP reading are due to Hospital tension and when the last BP reading was normal the doctor ignored the Creatinine test results.
So conclusion is that it is not something to worry about at all, but you may need to check it later after the process finish to assure that everything is fine.
My experience with the "White Coat Syndrome" was very funny though ;D ;D
