Testing for suspected COVID-19


The number of cases reported globally due to COVID-19 are rising. The first confirmed case in New Zealand was reported by the MOH late last week. The situation is being monitored closely and information is being updated on a regular basis.

Any patient who is suspected of having COVID-19 and being considered for testing should be discussed with and approved by the local Medical Officer of Health team.

Hospital inpatients within the BOP and Lakes DHB’s should be discussed with and approved by the local Infectious Disease Physician.
