my son is 5yrs old and has been unwell since last september. He has recurring viral infections, pains in his knees and feet, unexplained high fevers, sweats alot while sleeping, weight loss, very pale colour , coughing with 2 weeks, runny nose, no appetite, tires very easily. My gp has suggested doing monospot test to check or glandular fever but i think it sounds more like leukemia. Would leukemia show up in monospot test? Is monospot for diagnosing glandular fever?
