Kikky B. ★★★★★ : I had an amazing experience at Biosystems Diagnostics Centre. From the moment I walked in, the lab was so efficient , no long waiting, everything was organized and the equipment looked very modern and well-maintained. You can tell they invest in having a properly equipped facility. Special shoutout to the Sonographer Patience who did my ultrasound. She was incredibly polite, very gentle, and so skilled in her line of work. She explained everything calmly and made what could have been a stressful process very comfortable. Her professionalism really stood out. Overall, Biosystems will forever be a reputable diagnostics centre for me. I highly recommend them to anyone looking for quality, care and efficiency in one place.
Success S. ★★★★★ : I had a really good experience at Biosystem Diagnostics. The sonographer was so kind and professional and made me feel comfortable throughout the scan.

Femi O. ★★★★★ : Very good environment but there is a need for improvement on how the front desk works. I think they need more staff there. I waited for more than 1 hour to get a test done and the results were not delivered promptly as promised
Victoria H. ★★★★★ : The Centre is serene and well equipped but feels a bit short staffed with eminent delay in attending to clients. It also feels like a one off experience which can be the same on another day. Staff are friendly and professional

Victoria N. ★★★★★ : I would give them 0 stars if I could. The customer service was TERRIBLE. The staff member I interacted with was mean, rude, dismissive, and showed no empathy. There was no regard for customers at all. I do not recommend. The level of professionalism needs serious improvement.
EuroWestafrica Hi ★★★★★ : They could really hurt you before you even step in for an injection. It’s a risk to bring any one you love here. 0 star. Terrible people.

Grace A. ★★★★★ : It's disappointing that a big facility like this one has zero tolerance for patients lives and no appreciation of urgency. 6 years ago we brought our dad, a 71 years old man for an MRI scan only for an inexperienced staff who didn't know how to man the machine to be on duty. Results never came out till he passed on after paying so much. This past weekend, my daughter was rushed from boarding school for a knee X-ray. . 24hours after, The staff at the reception said the person to print it out had closed by 4pm. So report came out 48hours later despite the emergency. On Saturday she was taken for an MRI scan, inexperienced staff on duty was checking Google to be able to operate the machine! Jocking with someones life! The report is to come out on monday but if we pay extra10k (after paying 100k for the MRI) we will get a soft copy of the film in a CD right away, before monday. We paid. Only for the doctors to open the CD on Saturday and see nothing saved in it. Empty! Defeating the whole purpose of paying extra and costing us time for prompt medical attention! Intercontinental Diagnostics is just big for nothing. No competent staff there. Do better please, or shut down.
Obutor A. ★★★★★ : Horrible service. Zero regard for patients. I got to intercontinental diagnostics by 12.00noon on a Saturday, for an MRI on my niece. They kept us waiting till 2.30pm and when we protested, the person at the reception nonchalantly replied that it was no big deal, we can get angry, nobody will die. Complaint lines rang without anyone picking the calls. The radiologist spent initial 20 mins ( after. He had placed my niece on the machine) browsing the Internet for videos on how the MRI machine works. He was shuttling to and fro perfoming ultra sound scans between our procedure. Finally after 4 hours of nonchalance, intercontinental gave us an empty CD as our MRI result to present to the professor in charge of my niece. That is the worst diagnostic center ever.
