They couldn't take blood from a vein, it's a shame, such nurses shouldn't be at work, especially in a private clinic. They chose the time, paid off and left without tests, they had to make a refund. The veins are normal, they were taken everywhere without problems.
I have been using their services for many years, I am happy with everything. It is a pity that after the change of ownership, ordering via the Internet was deprived of the right to take tests out of turn.
