Statement	Section
The G6PD status of patients should be used to guide administration of PQ for preventing relapse. Good practise statement	Executive summary—page 11 Treatment of uncomplicated malaria caused by P. vivax, P. ovale, P. malariae or P. knowlesi—page 60
When G6PD status is unknown and G6PD testing is not available, a decision to prescribe PQ must be based on an assessment of the risks and benefits of adding PQ. Good practise statement	Executive summary—page 11 Treatment of uncomplicated malaria caused by P. vivax, P. ovale, P. malariae or P. knowlesi—page 60
Given the benefits of preventing relapse and in the light of changing epidemiology worldwide and more aggressive targets for malaria control and elimination, the group now recommends that PQ be used in all settings	Treatment of uncomplicated malaria caused by P. vivax, P. ovale, P. malariae or P. knowlesi—page 68
In the absence of quantitative testing, all females should be considered as potentially having intermediate G6PD activity and given the 14-day regimen of PQ, with counselling on how to recognize symptoms and signs of haemolytic anaemia	Treatment of uncomplicated malaria caused by P. vivax, P. ovale, P. malariae or P. knowlesi—page 69
If G6PD testing is not available, a decision to prescribe or withhold PQ should be based on the balance of the probability and benefits of preventing relapse against the risks of PQ induced haemolytic anaemia. This depends on the population prevalence of G6PD deficiency, the severity of the prevalent genotypes and on the capacity of health services to identify and manage PQ induced haemolytic reactions	Treatment of uncomplicated malaria caused by P. vivax, P. ovale, P. malariae or P. knowlesi—page 69
