Rabin Medical Center in Petah Tikva has asked 150 of its patients to undergo testing for HIV after a piece of hospital equipment may have been improperly cleaned.

Each of the patients in question underwent an endoscopy procedure with a device that may not have been sufficiently disinfected after it was used to examine an HIV-positive patient.

The Health Ministry said in a statement that the patients in question face the lowest of possible risk of infection and that the ministry supports the hospital’s decision to act cautiously and refer them for testing.
