What our customers say about us
I normally have an issue with my veins as they are very thin but the technician was experienced and the sample came out in one shot at the first attempt, which really reassured me.
The pickup was done extremely nicely. Got a message when the person started , no calls for directions and most of all extremely polite representative.
Got my one year old tested. Very professional and safe. Using sealed sample kits with needles, tubes and gloves pre-packed.
