AbstractTo study the effect of timing of urine collection in determination of microalbuminuria in
type 2 diabetic patiems, timed urine (night time and daytime) as well as spot urine (first morning
and random morning) samples were collected from 44 type 2 diabetic patients, 21 with norma
albuminuria and 23 with microalbuminuria. The methods of spot urine albumin expression for
microalbuminuria were also compared between albumin concentration (AC) and albumin to creati
nine ratio (ACR). Night time albumin excretion rate (AER) was 16 per cent lower and daytime AER
was 13 per cent higher than 24-h AER (p
