Most target substances for immunoassay of infectious disease are antigens or antibodies which do not exist in the human body. Therefore, the method to set reference values is different from chemistry or hematology testing. High sensitivity is required for infectious disease testing, particularly for screening. Also, its reference values (cut-off values) are set as low as possible. Therefore, a false-positive reaction can be caused due to slightly non-specific reactions in infectious disease reagents. The specificities for infectious disease reagents were evaluated with 9 kinds of HCV antibody test kit and 9 kinds of HIV screening kit...

The complement pathway is a cascade of proteases that is involved in immune surveillance and innate immunity, as well as adaptive immunity. Dysfunction of the complement cascade may be mediated by aberrations in the pathways of activation, complement regulatory proteins, or complement deficiencies, and has been linked to a number of hematologic disorders, including paroxysmal noctural hemoglobinuria (PNH), hereditary angioedema (HAE), and atypical hemolytic-uremic syndrome (aHUS). Here, current laboratory tests for disorders of the complement pathway are reviewed, and their utility and limitations in hematologic disorders and systemic diseases are discussed...

BACKGROUND: For the determination of creatine kinase (CK)-MB, the immunoinhibition method is utilized most commonly. However, the estimated CK-MB activity may be influenced by the presence of CK isoenzymes in some conditions like cancer. Thus, a CK-MB-to-total-CK ratio more than 1.0 could be found in such a situation. The study aimed to explore the relationship of cancer to high CK-MB-to-total-CK ratio. MATERIALS AND METHODS: From January 2011 to December 2014, laboratory data on all CK-MB and total CK test requests were extracted at Far Eastern Memorial Hospital (88,415 requests)...

In the past half-century, routine central laboratory testing has become increasingly automated and efficient. The majority of clinical chemistry, immunochemistry and hematology testing are performed using high throughput instrumentation, with sophisticated automation. Microbiology, immunohematology and molecular diagnostic testing are also becoming increasingly automated. Recent challenges in healthcare demand new diagnostic solutions worldwide. Point-of-care testing (POCT) offers considerable advantages over central laboratory testing, such as fast and simple specimen handling, and simpler sample requirement (no additives and mostly blood from finger stick; and urine)...

Somatic mutations of the spliceosome machinery have been recently identified by whole genome analysis in hematologic diseases, such as myelodysplastic syndrome, chronic lymphocytic leukemia, myeloproliferative neoplasms, acute myeloid leukemia, and advanced forms of mastocytosis, and also in nonhematologic conditions. SRSF2 is a member of the serine/arginine-rich family pre-mRNA splicing factors that plays a role in mRNA export from the nucleus and translation. We describe a high-resolution melting (HRM) curve analysis to screen for SRSF2 hotspot mutations in a fast, sensitive, and reliable way...

Irinotecan is a cytotoxic agent administered by IV infusion in the treatment of advanced colorectal cancer. Its anticancer activity results from its bioactivation into SN-38 metabolite, which is cleared through glucuronidation by the hepatic enzyme uridine diphosphate-glucuronosyltransferase 1A1 (UGT1A1). In the general population, there is wide inter-subject variability in UGT1A1 enzyme activity related to UGT1A1 gene polymorphisms. The French joint workgroup coming from the National Pharmacogenetic Network (RNPGx) and the Group of Clinical Oncologic Pharmacology (GPCO) herein presents an updated review dealing with efficacy and toxicity clinical studies related to UGT1A1 genetic variants...
