Cost of blood test/treatment for expat (Kuala Lumpur)

Dear everybody,

I have a health issue because of my thyroid which require a very regular treatment. I would like to know :
- How does a blood test cost in Malaysia?
- If, by all hazard, someone has the same problem, is it hard to find the treatment?
- If someone has any recommendation for an hospital (private or public) and a doctor (endocrinologist or generalist)?

Any information would be very welcomed. Thanks a lot and have a good day :)
