Dr. Attila Bezzegh

specialist in medical laboratory diagnostics and microbiology

Over his career he has led a reference laboratory, strengthened the teams of Roche Diagnostics and Beckman Coulter, served as medical director of the Corden lab network, and today is a consultant at Semmelweis University's Institute of Laboratory Medicine and head physician of a central laboratory.

What people ask most

Is the paternity test result legally valid?

Yes — for legal purposes, sample collection is documented and identity-verified, performed in an accredited partner laboratory. A private (informational) test with simpler sampling is also available.

How discreet is the process?

Completely. Every enquiry is handled with medical confidentiality, and the result is given only to the client. Consultations take place by prior appointment, in person.

How long does the result take?

It depends on the type of test — we give you the exact turnaround time at the first consultation, and deliver the result together with an expert interpretation.

What is FMT (microbiome therapy)?

Microbiota transfer therapy is a scientifically grounded method for restoring gut flora, which we carry out in collaboration with MicroBiome Bank. We advise on suitability in an individual consultation.
