This week’s Research Roundup highlights outcomes of warfarin therapy for bioprosthetic valve thrombosis of surgically implanted valves.

Mayo Clinic has one of the leading reference laboratories in the world that performs elemental analysis and metal testing for patients. Paul Jannetto, Ph.D., discusses Mayo's testing menu and services.

Mike Baisch, Systems Engineer at Mayo Clinic, discusses the mechanics of performing a staffing-to-workload analysis in the testing laboratories. There are three primary areas of focus with staffing needs: direct effort, indirect effort, and operational needs. This post focuses on indirect effort.

Chromosome analysis, which was once the preferred genetic test for a wide variety of congenital abnormalities, is now one of the most frequently misordered cytogenetic tests at MML. This "Specialty Testing" webinar will outline the differences in technologies and the appropriate use of each test.

Greg Widseth was suddenly hit by a rare disease that prompted his immune system to attack his brain cells, resulting in as many as 60 seizures a day. Special blood and spinal fluid tests developed by Mayo Medical Laboratories confirmed that Widseth had antibodies known to target certain brain cells.

In this “Hot Topic,” William Nichols, M.D., presents a case study that demonstrates how pre- and postanalytic variables of the patient and blood samples can have confounding effects on the laboratory evaluation of coagulation disorders.

The differential diagnosis for inflammatory bowel disease (IBD) includes irritable bowel syndrome (IBS). While the clinical presentation is similar, IBD is an inflammatory disease, while IBS is a noninflammatory disease. View this "Hot Topic" to learn about testing for IBD and IBS.

Membranoproliferative glomerulonephritis (MPGN) is a pattern of glomerular injury. Based on the etiology of MPGN, Drs. Sethi and Fervenza proposed a new histologic classification of MPGN into Ig/IC-mediated MPGN and complement-mediated MPGN. In this “Hot Topic,” Senjeev Sethi, M.D., Ph.D., demonstrates the use of the new classification with case studies.

In this “Hot Topic,” Bobbi Pritt, M.D., discusses how Lyme disease is the most common vector-borne illness in the United States and Europe and caused primarily by Borrelia burgdorferi in the United States, while B burgdorferi, B afzelii, and B garinii cause Lyme disease in Europe. We will also discuss using PCR and melting curve analysis to identify a new species of Borrelia.

In this “Hot Topic,” Elitza Theel, Ph.D., discusses how common cases of presumed Lyme disease go unreported each year and discusses scenarios in which testing for Lyme disease is indicated and reviews both recommended and inappropriate testing methodologies. The overall focus is on performance of the CDC endorsed two-tiered serologic testing algorithm and the latest CDC recommendations.

Helicobacter pylori (H pylori) infection is among the most common bacterial infections worldwide with approximately one-half of the world’s population infected. Several invasive and noninvasive testing methods are available to detect H pylori infection.
