Choked throat with high TLC. Hospital.

Hi, my mother was diagnosed with TB last year and after medication for 9 months, she was found to be alright and tested negative for TB two times for sputum sample. recently, in one if regular blood checkups, her TLC was elevated(report attached). her throat is choked and has not recovered even after a week of medication. she is being tested for infections and was found to be negative for dengue/malaria and swine flu. another thing to mention is that she has ILD and was being given steroid for same. she does not visibly has any issue nor she complains of any pain except some coughing and choked throat. her sugar came a bit high as well but apart from that, no one is able to identify the cause(which infection) of high TLC. could u please guide if she appears normal and nothing is alarming or there is cause to be worried and we should escalate to another hospital. also, how should we proceed ahead.
