The Hospital Authority said on Tuesday that it was following up with the supplier of a testing product after being notified by the firm last week about complaints elsewhere related to quality issues.
The product, supplied by Abbott Laboratories, is a reagent kit that detects the level of prostate-specific antigen (PSA) in blood. An elevated level may be a sign of prostate cancer.
The product's quality issues could 'potentially lead to a misdiagnosis of prostate cancer, causing doctors to erroneously consider unnecessary treatments', the authority said.
Two batches of the affected products were sent to Caritas Medical Centre in Sham Shui Po and Tuen Mun Hospital.

While Tuen Mun Hospital had not started to use the product, Caritas Medical Centre had already tested blood samples of 406 patients with the PSA kit since April 28.
It has reviewed the test results and will contact about 70 patients this week, and rearrange blood tests based on their clinical needs.

Hong Kong should allow cinemas to host live events to survive: lawmaker
Hong Kong should relax the licensing renewal criteria for cinemas to allow them to host live performances or sports broadcasts, a lawmaker has said, as the city continues to grapple with a slew of theatre closures. Advertisement Kenneth Fok Kai-kong, who represents sports, performing arts, culture and publication in the legislature, made the suggestion on Thursday after the Golden Harvest cinema at MegaBox shopping centre in Kowloon Bay announced it would be closing down at the end of the week. Fok said that while he believed the rate of closures was slowing down, he feared that residents would gradually stop going to the cinema to watch films, with fewer choices of theatres available to them. 'The government should consider relaxing the licensing requirements to allow cinemas to operate different types of businesses,' he said, citing live performances and live sports broadcasts as alternative events that would allow more theatres to survive. Fok added that box office revenues in Hong Kong were largely dependent on American films, with Hollywood blockbusters taking up 70 to 80 per cent of earnings. Advertisement As such, the current downturn in the United States box office was also affecting Hong Kong, he explained. US domestic ticket sales amounted to US$8.7 billion in 2024, down 3.3 per cent from US$9.04 billion the year before. According to the Hong Kong Theatre Association, only 51 cinemas were left operating in the city as of May, a sharp drop from the 112 venues in 1994.

Dragon boat races and the like must have proper waste management plans

Submissions should not exceed 400 words, and must include your full name and address, plus a phone number for verification Ahead of World Environment Day today, it was very disappointing to see the general lack of concern regarding waste at the Stanley dragon boat races last Saturday. Plastic Free Seas did the best we could with a last-minute mini collection to salvage at least some of the plastic bottles and metal cans for recycling, but only a small number of people brought them to us. We collected only 963 drink bottles and 758 drink cans, which is a fraction of what would have been used throughout the day. For the past few years, Sun Life, as a sponsor of the event, engaged The Green Earth to do a large-scale collection of recyclables at the Stanley races. Unfortunately, Sunlife was not the sponsor this year and recycling did not appear to be a priority at the event. Many plastic bottles (which should have been avoided in the first place), cans and cardboard boxes ended up going to landfill unnecessarily this year. It is unimaginable that such a large gathering of people for an outdoor event, particularly one at the beach, can be allowed to happen without convenient and sufficient provision of water refills and proper waste management in place. In order to reduce waste from these types of events, we strongly recommend the following.
