Max Bupa — claims rejected with foolish reason

I brought the max bupa health insurance policy 3 months back of rs 5 lacs for my parents. They recently got admitted due to dengue fever and we raised reimbursement claims for both.

They rejected both claims stating a foolish reason -
This is with reference to your e-mail appended below, we would like to inform you that your claim numbers 501904 and 501909 have been reviewed by our basis the documents shared by you we have observed that the pathological investigation verified by lab technician instead of md pathologist, which does not qualifies as an valid pathological test to carry on any treatment based on the findings of the same. Hence, we regret to inform you that we will maintain our earlier decision to decline the mentioned claim as per policy terms & conditions clause no. 6.30.

We followed our doctor and get the tests done and now max bupa is saying that the claims are not valid stating above reason. How a patient knows the degree of a laboratory owner or who is doing the tests?
