What is the IGM and IGG test for TB. The doctor suspected TB in my children. My son is 9 years and daughter is 7 years old. The IGM test on their blood test returned results of 1.12 and 1.23 respectively. Does this show the severity of the infection?The doctor has prescribed some more tests including x-rays etc.
Thanks for your question on Chat Doctor. I can understand your concern. IGM and Egg are antibodies produced by body. Egg reflects old infection. IGM reflects recent infection. So TB IGM when it is high, is suggestive of recent TB study. But it is not always diagnostic. So anti-tubercular Chat Doctor.  You should definitely get done other reports like chest x-ray, ultrasound examination of abdomen etc. for diagnosis of tb. So follow your doctors advice and get done other tests. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
