Health Measurements List

2021 NHANES Health Measurements

Below is a list of tests you may receive on the day of your examination. You will only have the test if your age falls within the ages shown in parentheses. You will receive the results of health measures shown with a black diamond (♦). Two diamonds (♦♦) means you will receive a result only if positive, or abnormal.

Before you enter the NHANES Mobile Examination Center

You will receive a Coronavirus Disease 2019 (COVID-19) Rapid Antigen screening test. ♦

Health Measurements

You will be weighed and measured (all) ♦

We will take your blood pressure (8+) ♦

Women and girls only:

Females 12-59 years old will have a urine pregnancy test, as well as girls 8-11 who have started their menstrual periods. Our medical staff will tell you if you are pregnant if you did not already know it.

Parents of girls younger than 14 years of age who are pregnant will also be informed of the result. ♦♦

After your visit to the NHANES mobile center:

You will be asked to participate in two dietary interviews by phone 3-7 days after your visit to the mobile center. All survey participants will be asked take part in the interviews. An adult will answer questions for children less than 5 years old and will assist children 6-11 years old. Participants 12 years and older will respond for themselves.

You, or an adult in your family (if you are between 1-15 years old), will also be asked about food shopping habits in a separate interview.

For each of these interviews you will receive a token of thanks for your time and effort.

Taking part in these interviews and health measures after your visit to the mobile center is voluntary. If you have questions about getting your results, please call 1-800-452-6115.
