<s>[INST] my son age 5 years,weight 22 kg,height 105 cms has 2-3 small lumps on the right side of his neck.so i did a montoux test,CBC, and T-IgM test.The MT test was nagative but the T-IgM test the reading as 0.91 which is borderline value.Does it mean that my son has TB and what is the diet for it. [/INST] Thanks for your question on Healthcare Magic. I can understand your concern. No, this value does now suggest active tuberculosis. These are antibodies against tuberculosis. They can be present if child is vaccinated with BCG vaccine in past. So borderline positive antibodies don't suggest TB. Simple viral upper respiratory tract infection (URTI)  is the most common cause for cervical Lymphadenopathy in children. So give him treatment for URTI for 1 week. His swellings will mostly reduced. Don't start anti tubercular drugs on this report. Give him plenty of fluids orally. Avoid oily and spicy food. Warm water gargles 5-6 times a day is also beneficial. Don't worry, he will be alright. Hope I have solved your query. I will be happy to help you further. Wishing good health to your son. Thanks. </s>
