Hi I was wondering if I can get a little help. I have an 18 yr old son due to rapid weight loss my doctor ordered blood test on results of the tests he then had to repeat the liver function test 2 weeks later he also had high blood platelets. The results have come back and he now wants to repeat the liver function 1 again in 4 wks time. I cant get no answers from receptionist ,asked for a call back from doctor and was just told a letter has been sent to me. I now have a very worried teenager who has learning difficulties and don't know what to say to him.
