My son is 4 years suffered from high fever 103 so Dr. told to take blood test report was elevated wbc and crp. Wbc is 19000 and crp is 76. So he put him o� antibiotics. For 7 days but after 2 days he is alright but now continuing the antibiotics. Dr. told to repeat the blood test but am very worried. I have google regarding end but it is shocking if elevated wbc is dangerous? Or only becoz of the fever the wbc is elevated? He is active and normal. Shall I repeat the test after 7 days. Is there anything serious ?
