Overview of the
Labeling Process
Labels
• Proper and accurate labeling is one of the most
important aspects of the study.
• Each woman, child, and man selected for the survey
will have their own individual set of labels.
• Each household and bakery will also have their own
individual set of labels.
• The label identifies the participant, household, or
bakery to the sample with a unique identifying
sequence of numbers and letters.
• This sequence of numbers and letters matches with
the barcode and provides key study information.
General instructions
• Do not use pencils or standard ink pens to write on the
label. Use a Sharpie permanent marker to complete the
date information on the label.
• The team supervisor will staple the labels to the
questionnaire as the survey participants are identified.
• The questionnaire and labels will accompany the
survey participant through the interview and sample
collection process.
• The questionnaire with the remaining labels should be
returned to the team supervisor before starting the next
household assessment.
• Read the labels carefully. Be sure to match the survey
participant to the label and to the correct item to be
labeled.

Team Supervisor
• The team supervisor will
paste the household
“Questionnaire” label on
the household
questionnaire, and staple
the rest of the household
labels to the questionnaire.
• The team supervisor will
then pass the household
questionnaire to the
interviewer to start
the interview.
Team Supervisor
• The same procedure is followed for the
woman, man, and child “Questionnaire”
labels.
• After stapling the labels
to the questionnaire,
the team supervisor
will write the
household number on
the first page of the
woman, man, or child
questionnaire.
• Pass the questionnaire
to the interviewer to
begin the interview.
Team Supervisor
• When the team supervisor sees that the nurse phlebotomist
is available for her first collection, the team supervisor will
send a woman participant for urine and blood collection
prior to questionnaire completion.
• The team supervisor will paste the woman “Questionnaire”
label on the woman’s questionnaire, write the household
number on the first page of the questionnaire, and staple
the rest of the labels to the questionnaire.
• The supervisor will then pass the questionnaire to the
nurse.
• After the nurse is done with the collection process, the
woman’s questionnaire with the remaining labels is passed
back to the team supervisor.
Nurse phlebotomist
• For the women participants,
the nurse phlebotomist will
use the Red Top, Purple,
Urine Cup, Urine 1, and
Urine 2 labels.
• The Red Top and Purple
labels are to be attached after
the blood is drawn.
• The Urine Cup and Urine
1,2 are placed on the cup and
cryovials prior to collection.
Nurse phlebotomist
• For the child participants,
the nurse phlebotomist
will use the Red Top and
Purple labels.
• The nurse will ask the
child’s name or ask a
mother to identify the
child before proceeding
with blood collection.
Nurse phlebotomist
For the men participants, the nurse
phlebotomist will use the Purple label.
Nurse phlebotomist
• Labels for blood collection are attached after the blood is
drawn.
• Labels need to be attached to the specimen tubes in a left to
right manner while holding the cap in the left hand such
that the label may be read. One hint is to have the bar code
look like a ladder if the vial is standing up.
Nurse phlebotomist
• Always leave the ruled
part of the tube free of a
label.
• For example, place the
label over the existing
tube label. For urine,
leave the graduated
numbers visible on the
cryovials.
Interviewer
• The interviewer will use
the flour 1, 2, 3 and salt
labels to appropriately
label the samples of flour
and salt collected in the
household.
Team Supervisor
The remaining labels will stay attached to the
questionnaires, which are given back to the team
supervisor.
Bakery collection
• The team supervisor will
interview and collect flour
samples from the local bakery
before leaving the cluster at
the end of the day.
• The “Questionnaire” label will
be pasted on the bakery
questionnaire and up to 3 flour
samples are to be collected.
• The remaining labels will stay
stapled to the questionnaire.
