Newborn and Pediatric Patients
Approximately 10% of ARUP’s testing is performed on specimens collected from pediatric patients. Because small specimen volumes can pose a challenge, ARUP has developed one of the largest pediatric databases in the laboratory industry.

 

New Test Highlight:

Rapid Whole Genome Sequencing (3005935)

ARUP’s new Rapid Whole Genome Sequencing panel is a comprehensive first-line test to determine the etiology of a patient’s symptoms in acute settings (e.g., the neonatal intensive care unit [NICU]) if a Mendelian genetic condition is suspected.

Trio testing from the proband (patient) and both parents enables optimal diagnostic yield and results interpretation. The panel examines the whole genome through massively parallel sequencing to quickly diagnose genetic disorders and provide the answers necessary for effective treatment. Final results are reported within 7 days, so you and the families you serve have the data needed to make informed choices.

Pediatric Laboratory Testing Frequently Asked Questions (FAQs)

Which ARUP laboratory tests can be used for pediatric patients?

Unless the word “adult” is used in the test name, most tests offered by ARUP Laboratories are suitable for pediatric patients. Pediatric-specific tests may be recommended in clinical situations when markers differ between pediatric and adult patients. In other clinical scenarios, age-specific reference intervals may facilitate correct interpretation. Pediatric-specific tests will generally include the words “children” or “pediatric” in the test name on the Laboratory Test Directory. Many tests include Ordering Recommendations in the Laboratory Test Directory that further clarify the populations for whom these tests are recommended.

How can I tell if a test is contraindicated for pediatric patients?

Tests that have the words “adult” or “adults” in the test name on the Laboratory Test Directory are generally not suitable for pediatric patients. For example, “Acute Lymphoblastic Leukemia (ALL) Panel by FISH, Adult” or “Testosterone (Adult Males or Individuals on Testosterone Hormone Therapy)” are not usually recommended for pediatric patients; in these cases, an alternative test appropriate for the patient’s age and clinical scenario should be ordered. For many tests, Ordering Recommendations in the Laboratory Test Directory provide guidance on the suitability of a test for a given clinical scenario and suggest alternative tests.

Are pediatric specimen volumes listed in the Laboratory Test Directory?

Minimum volumes required for each test are listed in the Laboratory Test Directory under “Specimen Required.” Unless otherwise noted, these minimums apply to both pediatric and adult patient samples. If available, additional acceptable specimen information may be found in the Specimen Collection and Handling instructions, which can be found as a PDF under the “Specimen Collection and Handling” icon on the Laboratory Test Directory.

Which ARUP tests have age-specific reference intervals?

If established for a particular test, age-specific reference intervals are listed in the Laboratory Test Directory under “Reference Interval” or provided on example patient charts. Many tests that do not have age-specific reference intervals may still be suitable for pediatric patients.
