| PRACTICAL POINTS FOR COLLECTING BLOOD, URINE AND STOOL SAMPLES IN CHILDREN
|
URINE
SAMPLE COLLECTION
- Urine
should be collected in a sterile plastic or glass bottle.
- The
bottle can be sterilized by washing it with soap & water
and then by boiling it in water for 10 minutes.
- Urine
sample should be mid-stream i.e. the initial small quantity
of urine should be discarded and the remaining sample to be
collected in the sterile bottle.
- First
or second urine sample should be collected.
- Urine
sample collected should be delivered to the laboratory within
1 hour of collection. If the time exceeds then the bottle should
be kept in a bag containing ice cubes until delivered.
- Urine

STOOL
SAMPLE COLLECTION
- Stool
sample for microscopic examination should be collected in a
sterile wide mouth plastic or glass bottle.
- Patient
need not be fasting as stool sample can be collected at any
time of the day.
- Sample
in the case of diarrhea should be delivered as soon as possible.
- The
quantity of the sample need not be in excess.
BLOOD
SAMPLE COLLECTION IN CHILDREN
- For
infants, the blood for analysis should be collected prior to
feed, as milky & turbid serum interferes with certain testing.
- Serum

clots and is kept in a sterile tube, bottle, which should be
kept in deep freeze until delivered to the lab.
- Blood
for CBC and sugar examination to be delivered to the lab immediately
after collection.
