Accidently hitting the wrong key on a computer sparked fears Covid-19 had returned to the region.
A Covid-19 test was accidently recorded as positive after a manual entry error.
Community Based Assessment Centre staff in Blenheim were alerted after the positive result was lodged at a laboratory in Nelson.
Staff discovered the mistake three hours later after lab staff checked the results.
The patient was not told of the positive result.
Medlab South Nelson Marlborough Clinical Microbiologist Dr Juliet Elvy says a manual entry error is to blame for the mix up.
“A manual entry error was made in recording the result for a Covid-19 test – due to a key stroke error.
“The incorrect test result was passed on to the Medical Officer of Health and that notification was withdrawn immediately after the error was detected – about three hours later.”
Southern Community Laboratories (SCL) run the labs at Nelson Hospital and Wairau Hospitals.
All Covid-19 swabs taken by the SCL run Medlab laboratory in Marlborough are sent to Nelson after first being processed at Wairau Hospital.
Dr Elvy says the error was detected before the incorrect result was given to the person who had been tested.
Processes have been changed in the wake of the incident.
“We now have processes in place which mean we no longer rely on manual entry of test results, and all validation of manually entered tests is done by a second scientist,” she says.
The member of staff had been doing an eight-hour shift at the lab when the error occurred.
Laboratories in both Marlborough and Nelson have been swamped processing Covid-19 swabs.
Between 13 and 23 August alone, a total of 3210 tests were done in Marlborough, Nelson and Tasman, including 902 in Marlborough.
The figures come from all test providers; community-based assessment centres (CBACs), GP clinics, after-hours clinics (urgent care) and hospitals and at Port Nelson.
Dr Elvy says staff have processed 10,000 Covid-19 tests from Nelson and Marlborough.
“ …this testing has significantly ramped up since community transmission was detected in Auckland earlier this month.
“We are doing all we can to support our staff who are meeting the unprecedented demands of Covid testing,” she says.
GM Strategy, Primary & Community Cathy O’Malley says Nelson Marlborough Health has full confidence in Medlab South during this unprecedented time.
