Max Hospital — Irresponsible lab technicians

Address:

House No.2, Street No.3,Lane No.6, Himadri Avenue, Jogiwala, Dehradun

My child is 9 months old.today I visited a pediatrician for my child in Max hospital dehradun and she advised us to give some blood sample of the child..we gave the blood sample around 11.30 am this morning and now at 2.30 pm I have recieved a call from the max hospital's lab technician asking us to come over again as the blood has been clot and they are unable to examine it.
Is this a professionalism? 9 months old has to go the pain again for the sample..and we live far from the hospital we have to come back again.this is really disgusting on the part of max hospital..how a blood can be clot as they should know when to process the blood.there must be delay in order to process the blood sample.
