It took a long time at the beginning to wait for the queue anyway.
The stages begin with a health background check and a brief explanation of the Rapid Test by the Doctor. Then proceed with blood draw. Then it ends with a blood pressure check, height, weight, and morning circumference.
I checked at 9 in the morning and the results were out at 2 in the afternoon. The results are notified via SMS and can be checked online. For test results and printed health certificates, you can do it at 5 pm or just come the next day if you don't have time
