Table 5. Challenges and lessons learnt.

Challenges: Challenges experienced in the initial implementation of HIV drug resistance testing	Lessons learnt: Some of the solutions applied to overcome initial challenges
High staff turnover.	Building capacity through training grant application.
Insufficiencies in the supply chain management.	Strategic memorandum of understanding with the suppliers.
Lack of functional laboratory network for sample flow, hence sub-optimal utilization of the facility	Instruments suboptimal utilized can be leveraged to be used for other services.
Financial sustainability due to decreased funding.	Engagement of key stakeholders.
Frequent electricity disconnection	Need to build relationship with other laboratories.
Premixed PCR reagents kit, limiting flexibility for use with other tests
