In this month’s “Hot Topic,” Elitza Theel, Ph.D., will discuss the detection of (1→3)-β-D-glucan (BDG) in serum as a biomarker for the presence of invasive fungal infections.
In this month’s “Hot Topic,” Curtis Hanson, M.D., will discuss the use of laboratory-based prognostic markers in patients with chronic lymphocytic leukemia (CLL). He will also highlight the importance of molecular analyses for IGHV and TP53 sequencing in these patients.
Multiplex PCR for Microbial Detection in Spinal Fluid (BIOFIRE FILMARRAY Meningitis/Encephalitis Panel)
In this month’s “Hot Topic,” Robin Patel, M.D., discusses the FilmArray meningitis/encephalitis (ME) panel, describing the panel, her experience with it, and an algorithm for its use.
Antibodies to aquaporin-4 and myelin oligodendrocyte glycoprotein (MOG) are recently described biomarkers seen in a subset of atypical optic neuritis which have revolutionized our understanding of the condition. In this “Hot Topic,” my colleague, Dr. John Chen, will review these advances and how they impact the clinical care of our patients with optic neuritis.
Cytomegalovirus Antiviral Resistance Testing: A New Assay for Detection of Mutations Associated with Antiviral Resistance in CMV
Cytomegalovirus, or CMV, is a common cause of disease in the transplant population. In some patients who are diagnosed with CMV and are on antiviral treatment for infections, the virus may develop resistance to the drugs. This “Hot Topic” will provide an overview of a new test developed by Mayo Clinic Laboratories, which uses next-generation sequencing technology to identify mutations in the genome of CMV that may be associated with antiviral resistance.
In this month’s “Hot Topic,” Julia Lehman, M.D., will discuss a rare and potentially fatal mucocutaneous blistering disease that is often associated with an underlying malignancy, called paraneoplastic pemphigus. She will also discuss the specialized tissue and serum testing that is required to establish the diagnosis.
In this month’s “Hot Topic,” Rajiv Pruthi, M.B.B.S., will discuss different types of hemophilia along with their pathologic basis. He will also cover various types of factor assays such as one stage and chromogenic factor assays for diagnosis and their role in management of hemophilia.
In this month’s “Hot Topic,” Brad Karon, M.D., Ph.D., will cover the need and evidence behind following the order of draw recommendations for routine blood collection. Specifically, does evidence demonstrate a need to collect serum tubes before either potassium EDTA or citrate tubes?
Matrix-Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry in Clinical Microbiology
In this month’s “Hot Topic,” Robin Patel, M.D., discusses how matrix-assisted laser desorption ionization time of flight (MALDI TOF) mass spectrometry works for bacterial identification, including the strengths and limitations of this technology. She also covers Mayo Clinic’s experience with the technology in the clinical laboratory.
In this month’s “Hot Topic,” a group of clinical laboratory technologists from Mayo Clinic’s Component Laboratory discusses a new tool to help standardize acceptable color variation for plasma products.
In this month’s “Hot Topic,” Robin Patel, M.D., will discuss the importance of accurate diagnosis of prosthetic-joint infection and its management, focusing on the pathogenesis, clinical presentation, and definition of arthroplasty failure, as well as discuss diagnostic strategies.
In this month’s “Hot Topic,” Robin Patel, M.D., will discuss the bacteria that cause pertussis, also known as whooping cough. Pertussis is highly contagious and spreads rapidly through families, schools, and hospitals. While adults and children may have relatively mild symptoms, the disease can be deadly for infants and newborns.
In this month’s “Hot Topic,” Brad Karon, M.D., Ph.D., describes how pseudohyperkalemia has many causes, from collection techniques, processing, and even transport. This presentation focuses on the various preanalytic and analytic causes of pseudohyperkalemia and what you as a phlebotomist can do to prevent it.
