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)

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 Stool labels only used for children and urine labels only used for women Use of the label Number of labels Type of specimen Field use: Data collection form 1 Microtainer 1 Blood Malaria slide 1 Blood DBS card 4 Blood Urine cup* 1 Urine Urine cryovials* 2 Urine Stool cup  1 Stool Stool tube  1 Stool TOTAL COPIES OF ID NUMBER 12

NCD Clusters These labels are in addition to all the labels needed for the 94 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 in 6 NCD clusters Women and Children in Nutrition remaining 94 clusters Salt in all 100 clusters 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!
