Urine albumin excretion measured over consecutive weekends and on repeated first morning collections from normal children showed considerable variation both during the day and from day to day in each subject. The results emphasise the need for repeated measurement of albumin excretion in children to confirm the presence of persistent microalbuminuria.
INTRODUCTION We hypothesized that patients are poorly informed about proper procedure for 24-hour urine specimen collection and its relevance in determination of biochemical analytes, despite availability of leaflets and webpage with instruction for collection. The aim of this survey was to question outpatients how well are they informed about procedure of 24-hour urine specimen collection. M...

Objective To determine if a simple stimulation method increases the rate of infant voiding for clean catch urine within five minutes.Design Randomised controlled trial.Setting Emergency department of a tertiary paediatric hospital, Australia.Participants 354 infants (aged 1-12 months) requiring urine sample collection as determined by the treating clinician. 10 infants were subsequently exclude...
Further experience with the differential ferrioxamine test (Fielding, 1965) for the measurement of body-iron chelation has led to modifications which include (1) an improved standard for the estimation of ferrioxamine, (2) simplified preparation of the test dose, (3) restriction of fluid during the test and (4) simplified methods of calculation. The principle of the test remains the same: an in...
The purpose of the present study was to determine whether children experience a higher systemic exposure to isoflavonoids when consuming a body weight-adjusted dose of soya compared with adults. Forty study participants were recruited from a local Waldorf school, including twenty-one children and nineteen adults. Participants collected a baseline urine sample and ate immediately thereafter a bo...
In the 70ies of the last century, ther term "preanalytical phase" was introduced in the literature. This term describes all actions and aspects of the "brain to brain circle" of the medical laboratory diagnostic procedure happening before the analytical phase. The author describes his personal experiences in the early seventies and the following history of increasing awareness of this phase as ...
BACKGROUND In drug-resistant TB settings, specimen collection is critical for drug-susceptibility testing (DST). This observational study included multiple specimen types collected from pediatric TB suspects with the aim to determine diagnostic yield and inform clinical practice in children with drug-resistant and drug-susceptible TB. METHODS From 03/2009-07/2010, TB suspects aged ≥6 months a...
Thalassinos, N. C., Leese, B., Latham, S. C., and Joplin, G. F. (1970). Archives of Disease in Childhood, 45, 269. Urinary excretion of phosphate in normal children. In 55 normal children on a normal diet, the phosphate and creatnine were estimated in a fasting 2-hour urine collection and in a simultaneous blood sample. In comparison with adults, a high serum phosphate and relatively decreased ...
OBJECTIVES The detection of an STI agent in a urogenital tract (UGT) specimen from a young child is regarded as being indicative of sexual abuse. However, the probabilities of contamination events that could conceivably lead to STI positive specimens in the absence of sexual contact are unclear. The objective was to estimate the potential for fingers that have come in contact with Chlamydia tra...
