經歷詳述:
My son went to see him for asthma for 5 times (from 2010 Nov to Dec) & so far I found his medical advice is reasonable. Until Dr. Tseng suggested my son to take the skin allergy test, I sought the advice from my friends & nurse that for allegy test, it could also be done by blood test.

I mentioned this to Dr. Tseng who gave me black face & started to say that Bio-Txx company is bad & cannot trust. I said you have advised my son to take allergy test which was his advice. He kept on saying bad things about that co. For me, it's up to you to give advice but don't ever say to your patient that it is wasting time & asked me to seek my specialist in respiratory medicine (Dr. Leung who is a very professional doctor). I just stopped him for further discussion but to focus on the asthma treatment for my son, he told me that my son could continue the inhalation for 2 weeks or stop the inhalation now as he saw some improvement but not totally satisfactory and it's up to my decision. What??? It is so ridiculous, I'm paying you for thousand dollars for medical advice & don't give me this reply. I found he is very irresponsible & unprofessional as a doctor & this is the bad experience for me & my son ever!!!!

I would surely relay this case to the appropriate authority for follow up.
