Katalyst Health 

Great experience. Did our PCR tests at Nuffield health centre at 3pm and were expecting our results before midnight the following day. We had the results back quickly and efficiently within 3 hours of having them done! So pleased with the speedy service.

Very good service

Had a pcr test before flying back to hk. Quick and good service.

Actually, we purchase a 3 hours rapid PCR test. However, we got the report 4 hours after we did the test. Luckily we reserve more time before the flight.

very nice and patient. Thanks a lot

Lab staff did excellent job – "4-hour" test completed in under two hours.

Registration process was confusing – having registered once, there was an instruction buried in a very long "confirmation" email to register for a second time.

I turned up at the centre unaware of that requirement, and had lost my camera phone. Fortunately, the receptionist was very understanding and completed the second registration on his computer, and waved me through.

THEY NEVER GIVE YOU YOUR REFUND BACK! I cancelled the booking a week in advance, I have rung them 20 times, I have sent them 10 emails. No one replied.
I asked for the refund and I am just ghosted. This is very unprofessional, it’s like they would never give you a refund.

Very quick and easy. Friendly staff

Excellent service and friendly helpful staff

Needed a PCR …easily booked and paid for on line, excellent service with a quick result. Thank you!

The whole process was fast easy and efficient. Booked on the day was seen within

Never got my results. Called over 10 times and there was no answer. Had to go to another company before I could fly.

Timely test result but my passport details were wrong so just as well I didn’t get asked to prevent it

Excellent service! Really friendly staff, who were helpful and accommodating. We were put at ease, the test was quick and we got results emailed within 15 minutes. Would definitely recommend.

Great service as booked last minute and results within 5 hours

Had a really negative experience with ExpressTest and thank goodness Katalyst were there to remedy a very stressful situation. So quick and professional - I couldn't recommend enough

I am really grateful to Katalyst Health for bailing me out. I got turned back from my flight because I did not present a covid test certificate. I needed one to present the following day. I almost missed the flight again. Thank goodness Katalyst did it for me same day at a really affordable price.
