Does The IGM Results Of 1.2 Shows Severity Of Infection?

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 Healthcare Magic.
I can understand your concern.
IgM and IgG are antibodies produced by body.
IgG 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 drugs should not be started only on the basis of positive IgM report.
You should definitely get done other reports like chest x ray, ultrasound examination of abdomen etc for diagnosis of tb.
So follow your doctor's 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.
