Specialized immunofluorescence testing helps uncover rare autoimmune blistering diseases, identify underlying cancers, and guide precise treatment, improving diagnostic accuracy and outcomes for patients with challenging skin disorders.
Mayo Clinic Laboratories has introduced a revolutionary diagnostic test for bile acid malabsorption, a significant contributor to chronic diarrhea. Developed by Dr. Michael Camilleri and Dr. Leslie Donato, this new bile acid malabsorption panel simplifies diagnosis and improves patient care by eliminating the need for special diets or prolonged stool collection. The test's effectiveness has been validated internationally, offering new treatment avenues for patients. Discover how this innovative test is transforming clinical practice and enhancing patient outcomes.
Looking to elevate laboratory operations, Yuma Regional’s hospital directors established a leadership model that pairs medical and administrative leaders, resulting in a changed perception of the laboratory’s ability to drive profitability and a $40 million capital investment in laboratory infrastructure.
In a quiet suburb outside of Minneapolis, Minnesota, an ordinary Saturday took a sudden and alarming turn for Scott Olson when he began experiencing symptoms of ventricular tachycardia. Central to the care and treatment he'd receive at Mayo Clinic was the precise testing that was done by Mayo's Cardiac Pathology Lab, which uncovered the true cause of his erratic heart rhythm. That discovery not only clarified Scott's diagnosis, but also highlighted the critical role that advanced diagnostics plays in guiding successful patient outcomes.
Central nervous system infections, such as meningitis and encephalitis, can be devastating for affected patients. While specific treatments are available for some of these infections, it first requires identifying the precise cause of infection. To meet that need, Mayo Clinic Laboratories has developed a metagenomics assay that can identify more than 1,000 pathogenic organisms in cerebrospinal fluid. The innovative assay, which uses an approach known as shotgun metagenomic sequencing, is one of the only such tests currently available.
Situated in a sprawling geographic region in mid-Missouri, Boone Health expanded its reach to improve access to high-quality holistic care throughout the area, improving the health of community members and increasing net revenue along the way.
What started as a persistent headache for Spencer Lodin soon devolved into slowed speech, seizures, and hallucinations, symptoms which stumped ER doctors into thinking he had meningitis or was suffering from psychosis. Finally, specialized testing at Mayo Clinic identified Spencer's condition as GFAP-IgG associated autoimmune encephalitis, which allowed for targeted treatment and a full recovery.
Mayo Clinic Laboratories introduces the Inherited Parkinson’s Disease Gene Panel (Mayo ID: PARDP), a collaborative breakthrough poised to transform Parkinson’s disease diagnosis and treatment. Led by Rodolfo Savica, M.D., Ph.D., and Zhiyv (Neal) Niu, Ph.D., this comprehensive test offers unparalleled insights into Parkinson’s genetics, unveiling novel gene associations and enhancing diagnostic precision through next-generation sequencing. The panel’s capabilities include detecting subtle genetic variations and identifying familial patterns, promising personalized medicine advancements.
Since 1992, cases of colorectal cancer have been on a slow decline, yet 52,550 people died from it in 2023. At Mayo Clinic, a cutting-edge menu of both germline (inherited genetic alterations) and somatic (tumors due to non-inherited genetic alterations) testing are two critical tools helping to improve targeted treatments for colorectal and other common gastrointestinal cancers.
Dr. Linda Hasadsri’s firsthand encounter with the genetic tests she’s helped develop has provided rare insight into testing quality and implications, enhancing their ability to advocate for the value of testing and infusing their work with deep empathy.
Recognizing the powerful role genes can play in diagnosing illness and guiding treatment, the Division of Laboratory Genetics and Genomics at Mayo Clinic spearheaded a testing expansion, implementing and upgrading more than 60 advanced sequencing and biochemical assays in 2023 and planning for even more this year.
Prevented from providing testing services to its community members due to a non-compete agreement with a national laboratory, Kootenai Health laboratory leaders deepened their relationship with Mayo Clinic Laboratories, receiving tactical support and guidance to launch an in-house reference lab just days after the non-compete agreement expired.
Multiple doctors and multiple examinations could not figure out why Lauri Sieben had spent much of her life “never feeling quite right” physically. Fortunately for Lauri, that changed after her daughter Christy began working as a genetic counselor in Mayo Clinic’s Molecular Technologies Laboratory. After seeing similarities between the patient testing she was performing for the lab and the physical symptoms being experienced by her mom, Christy took a leading role in getting Lauri to undergo molecular and biochemical testing at Mayo Clinic. The results of that testing not only provided much-needed answers, but a promising path forward for Lauri.
