Adan Hospital Lab

Hi everyone. I wanted to know the timings of the Adan hospital laboratory.

Google shows that it's open in the evening 4 to 7. A friend said that they take outpatients in the morning only and one said they close at 3pm. One said it is open 24/7. No one knows for sure. I have a lab request form from the doctor at Adan. (It is a blood test and not for any visa procedure.) I can go only after 4. 30pm, that's why the confusion.

If anyone has any information it will be a lot of help.
