Optimising Diagnostic Capacity for COVID-19 Testing in Nigeria

Posted: 14-04-2020 10:12:55 AM

Globally, the number of COVID-19 cases recorded has hit nearly two million across more than 200 countries and territories. This exponential rise is an indication of more COVID-19 tests being carried out across the globe to promptly detect the disease. However, increasing demand and global shortage of commodities has led to challenges bordering on prevention, detection and response in several countries.

Following reports of the coronavirus disease in Wuhan, China in December 2019, the Nigeria Centre for Disease Control (NCDC) promptly initiated measures to strengthen the country’s preparedness for early detection and timely response to the disease. This included strengthening in-country diagnostic capacity for the testing of COVID-19 by leveraging on existing laboratories within the NCDC molecular laboratory network. Initially, five laboratories were activated in the Federal Capital Territory, Abuja (1); Lagos state (2); Osun state (1); and Edo state (1).

In under four months, additional six laboratories have been activated for the testing of COVID-19 in Nigeria to cater to each geo-political zone in the country. This is critical because as of the 13th of April 2020, at least one confirmed case has been reported in all six geo-political zones in Nigeria across 19 States and the FCT.

The NCDC continues to expand diagnostic capacity for COVID-19 with the aim to add four more laboratories by the end of the week once all accreditation processes have been concluded. This expansion will significantly improve the national daily testing capacity, proximity from States’ sample collection centres to the nearest laboratory and ultimately, enhance the turn-around time from when samples arrive at the laboratory.

The list below categorises COVID-19 testing laboratories by their locations and operational status in Nigeria:

Name / Location of laboratories --- Location --- Operational Status

5. Irrua Teaching Hospital --- Edo --- Activated

6. African Centre for Genomics of Infectious Diseases --- Osun --- Activated

7. University College Hospital Virology Laboratory --- Oyo --- Activated

8. Federal Teaching Hospital, Abakaliki --- Ebonyi --- Activated

9. Defence Reference Laboratory --- Abuja --- Activated

10. National Veterinary Reference Laboratory --- Plateau --- Activated

11. Aminu Kano Teaching Hospital --- Kano --- Activated

12. DNA laboratory --- Kaduna --- In progress

13. University of Maiduguri Teaching Hospital --- Borno --- In progress

14. University of Port Harcourt Teaching Hospital --- Rivers --- In progress

15. TAMRED Laboratory --- Sokoto --- In progress
