Nurses have a very light hand (unlike most other clinics and laboratories in the city), blood collection takes place in a special chair. Also, the staff is perfectly prepared for the unexpected, tested on their own first-ever fainting spell :)
They close earlier than indicated. Which is very critical when you fly running to Yerevan from another city, arrive 10 minutes before closing time for all traffic jams in Yerevan and it is already closed
But the staff is very nice
I went several times and did several tests, and here's what I noticed: They will pick up a set of tests so as to make the most of you. For example, you can make a complex for a low price, and you will be offered a separate one for a higher price.
