Thyrocare — wrong reporting of tsh levels

Website:

www.thyrocare.com

I got my tsh level tested on 27th feb 2018. Thyrocare report gave a value of 6.48 which was much above the higher limit of 5.5. I was not satisfied as i had never got high tsh value earlier. So i cross checked by repeating the test next day by dr lal pathlabs. They reported a very normal vaue of tsh as 3.07.
I am highly shocked by thyrocare's wrong reporting. I asked the technician to escalate the complaint to lab. But he said they are giving lame excuses of circadian rhythm etc. Samples were just one day apart and both around 9 am as the reports have mentioned. So no variation in circadian rhythm is possible.
I want my money to b refunded. I had to shell out another 600 rs just bcoz of thyrocare's carelessness n incompetence.
Plus had i trusted thyrocare report don't know what would have happened to my health due to unnecessary medications.
