Specimen:
  • Capillary blood specimen collected by Laboratory on INMSP form. 
  • Instructions for collection technique on the INMSP form must be carefully followed to avoid rejection of the specimen. 
  • The specimen should be collected when the infant is more than 24 hours old and less than 5 days, but must be collected prior to discharge. 
  • A repeat specimen must be collected within 14 days of age when the first specimen was collected prior to 24 hours after birth.
Processing:  Send to University Hygienic Laboratory, Des Moines.
Performed: 7 days
Reference value: See State Laboratory report for reference values.
Method:

Phenylketonuria: No longer reported separately 9/3/05 included in Expanded Screening  Disorders.

Comment:  

If the State lab requests the patient to be retested due to the results from the initial testing, Laboratory staff can order the NEONT MET SCR RPT*, Misys order code NNTR. Neont Met Scr Rpt* is not orderable from PowerChart. Lab must order.  Connected to the Misys order code NNTR is a processing fee only. The NNTR is not to be used when a second collection is required due to an error in the collection process.   Recollection due to a lab error should be the Misys order code NNT with the first test being credited. Nursery is to notify ER as to which baby will be returning. A repeat INMSP form will be provided to the Lab by the State Lab. A repeat specimen must be collected within 14 days of age if the first specimen was collected prior to 24 hours after birth.
