New tests launched in May 2017 by Mayo Medical Laboratories:


Bacterial Typing by Whole Genome Sequencing (ID: BTWGS)
Useful For: 

  • Aids in investigation of a potential outbreak by a single bacterial species
  • May assist in identification of recurrent infection in an individual patient

Luteinizing Hormone (LH), Pediatrics, Serum (ID: LHPED)
Useful For: Diagnosis of precocious puberty and delayed puberty in children


Lysophosphatidylcholines by LC MS/MS, Blood Spot (ID: LPCBS)
Useful For: Second-tier newborn screen for X-linked adrenoleukodystrophy (X-ALD)


Mitochondrial Nuclear Gene Panel by Next-Generation Sequencing (NGS) (ID: MITON)
Useful For:

  • Diagnosis of the subset of mitochondrial disease that results from mutations in the nuclear-encoded genes
  • A second-tier test for patients in whom previous targeted gene mutation analyses for specific mitochondrial disease-related genes were negative
  • Identifying mutations within genes of the nuclear genome that are known to be associated with mitochondrial disease, allowing for predictive testing of at-risk family members

Newborn Screen Recommended Panel, Blood Spot (ID: NBSR)
Useful For: Presymptomatic identification of Recommended Uniform Screening Panel (RUSP) disorders only to allow for early initiation of treatment and consequent improvement in the long-term prognosis of affected patients


Newborn Screening Expanded Panel, Blood Spot (ID: NBSE)
Useful For: Presymptomatic identification of disorders for which we can screen using an expanded panel to allow for early initiation of treatment and consequent improvement in the long-term prognosis of affected patients


Prostate Health Index (phi), Serum (ID: PHIND)
Useful For: Aids in distinguishing prostate cancer from benign prostate conditions in men 50 years of age and older with total PSA results in the 4 to 10 ng/mL range and digital rectal examination (DRE) findings that are not suspicious for cancer


Zinc Transporter 8 (ZnT8) Antibody, Serum (ID: EZNT8)
Useful For:

  • Clinical distinction of type 1 from type 2 diabetes mellitus
  • Identification of individuals at risk of type 1 diabetes (including high-risk relatives of patients with diabetes, and those with gestational diabetes)
  • Prediction of future need for insulin treatment in adult-onset diabetic patients
