Sample Collection Procedures
How to Obtain Newborn Screening Filter Paper Forms:
NBS Filter Paper Forms (Lab-10) can be obtained at your local parish health unit.
- Blue Border Lab-10 forms are for patients covered by Medicaid, including those in the Kid-Med program and may be obtained from the health unit at no cost.
- Red Border Lab-10 Forms are for private and non-Medicaid patients. The price for these forms is $30.00 each.
- Private providers should obtain a mix of red and blue Lab-10 forms from their local parish health unit (or OPH Regional Office for certain areas) to match the Medicaid/non-Medicaid composition of newborns to be screened at their facility.
When to Collect a NBS Specimen:
- All newborns should be screened prior to hospital discharge regardless of their length of stay. Newborns remaining in the hospital for an extended period should be screened initially no later than 7 days after birth.
- Specimens should be collected 24 hours after birth. If specimen is collected prior to 24 hours from birth, the newborn must be rescreened at the first medical visit, preferably between one and two weeks of age, but no later than the third week of life.
- Whenever possible, a heel stick specimen should be collected prior to blood transfusion because transfusions can alter all newborn screening results. If a specimen is collected after a blood transfusion, repeat testing should be performed:
- 3 days after the last transfusion to detect congenital hypothyroidis
- 90 days after last transfusion to detect sickle cell disease, biotinidase deficiency, and galactosemia
