Labeling procedures
for the 2005 PNG
National Nutrition Survey
Why do we need labels?
•To help us link the data collection forms with
the specimens collected
For example:
We need to link the child’s form and the
information on the form with their stool,
malaria slide, dried blood spot card.
• The label ID number will be used to match
the data on the data collection form for
each person with the results of the
laboratory testing of the specimens.
• Each survey participant needs to have
their own ID.
• If 2 people had the same ID number what
might happen??
Types of Labels
• Labels for women’s samples (10 labels)
• Labels for children’s samples (9 labels)
• Labels for salt samples (2 labels – one for
the salt sample bag and one for the
household (HH) questionnaire)
Women’s labels
• Women’s questionnaire
• Red top Vacutainer tube (Research/Validation
study in POM only)
• Purple top Vacutainer tube (Research/Validation
study in POM only)
• Microtainer
• Malaria slide
• Dried blood spot (DBS) card
• Urine cup and two cryovials
Children’s labels
• Children’s questionnaire
• Red top Vacutainer tube (Research/Validation
study in POM only)
• Purple top Vacutainer tube (Research/Validation
study in POM only)
• Microtainer
• Malaria slide
• Dried blood spot (DBS) card
• Stool cup and tube
Procedure
• Remember: Make sure all of the materials
for the patient you are working with are
labeled before drawing blood or collecting
samples
• SOP (Standard Operating Procedure)
What do labels look like?

ID number
Remember!
• If the data collection form ID does not match
the survey participants ID then the results will
not be usable, and the team will have wasted
time and money and caused patient
discomfort for nothing.
How many labels will each
person have?
• Since each survey participant will have
multiple specimens there will be several
labels with the same ID number
• In the 94 clusters nationally each ID will
have 12 labels
• In the 6 NCD clusters each ID will have 24
labels
94 national clusters

Types of labels
There are 3 different sets of labels
1 set of labels for the NCD clusters
1 set of labels for the 94 clusters
1 set of salt labels
Label series

Women and Children

Salt in all 100 clusters
7000-9999
We only need to use a label for certain kinds of
specimen collection.
Men have no specimens collected, so they NEVER
need any labels.
Why do we have different sets of
labels?
We have different sets so that just by looking at the
code on the label we know whether that person was
from the 6 NCD clusters and had all of the additional
specimens collected, OR if that person was from the 94
clusters.
We do not want to waste labels. If we had the same
labels for everyone that would mean that for people in
the 94 clusters there would be 9 labels we would not
need!

Role of the interviewer
• 1) paste a “data collection form” label on the
forms of all children and women in the survey
• 2) Staple the rest of the labels for that
participant to the top of their data collection
form for the lab person
• 3) Paste salt labels on the household collection
form when salt is collected form a household
Don’t forget!!!!
• Every single child and woman and salt
sample needs a separate ID
• The interviewer is responsible for ensuring
that this happens!
