Table 2.

Appropriate study sample volumes according to age, and sample type. ‘T’ is time of sampling in hours since recruitment.

Age category	EDTA (T=0)	Plasma (T=24,48,72,96h)
Infants and Young children (<5y)	1-2ml	0.5ml
Older children (5-12y)	2-6ml	1-2ml
Adolescents and adults (>12y)	6-10ml	3-5ml

The volume of blood obtained (for both children and adults) will be documented at the time of recruitment and sampling. Consent will be sought to use residual EDTA samples for the evaluation of emerging, rapid methods of bacterial detection and antimicrobial resistance identification.
