Clinical importance of laboratory biomarkers in liver fibrosis

Hepatic cirrhosis is a major health problem across the world, causing high morbidity and mortality. This disease has many etiologies, yet the result of chronic hepatic injury is hepatic fibrosis causing cirrhosis and hepatocellular carcinoma, as the liver’s architecture is progressively destroyed. While liver biopsy is currently the gold standard for fibrosis staging, it has significant disadvan...

A sudden creatinine increase: A case report

Creatinine and estimated glomerular filtration rate (eGFR) are first-line laboratory parameters in the diagnosis of various renal diseases. In recent decades, cystatin C (cysC) has furthered the laboratory repertoire regarding renal status assessment and has been implemented in many clinical guidelines. Accordingly, with the establishment of cysC as a renal routine biomarker, further opportunities...

Underfilled blood tube containing EDTA

Introduction Blood samples having inappropriate volume are a substantial part of preanalytical errors. Inadequate sample volume for glycated haemoglobin (HbA1c) test may be a common problem of patients with diabetes mellitus having vascular changes. In this study, we compared HbA1c concentrations of underfilled and appropriately filled blood collection tubes. Materials and methods To compare Hb...

Defining laboratory medicine, or squaring the circle?

In the August 2020 issue of Clinical Chemistry and Laboratory Medicine, Giuseppe Lippi and Mario Plebani proposed a definition of laboratory medicine, which ends with this sentence: “The results of these measurements are translated into actionable information for improving the care and/or maintaining the wellness of both a single individual and an entire population”. Nevertheless, the selfishn...

Complete blood count alterations in COVID-19 patients

Coronavirus disease 2019 (COVID-19) pandemic represents a scientific and social crisis. One of the main unmet needs for coronavirus disease 2019 is its unpredictable clinical course, which can rapidly change in an irreversible outcome. COVID-19 patients can be classified into mild, moderate, and severe. Several haematological parameters, such as platelets, white blood cell total count, lymphocytes...

Extracellular vesicles and glycans

Highlights • Biological fluids contain nano-sized particles called extracellular vesicles • Extracellular vesicles properties reflect the physiological and pathological state of the parent cells • Extracellular vesicles as analytes are suitable for use in liquid biopsy-based real-time diagnostics • Glycans, complex oligosaccharides, are distinct components of extracellular vesicles mem...

Glucose inhibitor tubes in Croatian laboratories: are we doing well?

Introduction Reliable and accurate measurement of blood glucose concentration is of crucial importance for making clinical decisions in diagnosis diabetes, gestational diabetes and impaired fasting glucose tolerance. Materials and methods Survey was performed in form of questionnaire. Questionnaire was sent to all Croatian laboratories (N = 204) in electronic form using SurveyMonkey cloud-bas...

Preanalytical, analytical and postanalytical considerations in circulating microRNAs measurement

Highlights • Methods used for miRNAs expression profiling are quantitative reverse transcription polymerase chain reaction, microarrays, next generation sequencing and droplet digital PCR • To obtain reproducible and accurate miRNAs expression profiling detection, it is crucial to strictly standardize the entire process, starting from choosing the specimen type until the normalization strate...

Antiphospholipid antibodies in patients with antiphospholipid syndrome

Highlights • Antiphospholipid syndrome is a rare systemic autoimmune disease characterized by recurrent pregnancy morbidity or thrombosis in combination with the persistent presence of antiphospholipid antibodies in plasma/serum • Specialists in laboratory medicine should take responsibility for the entire analytical process, so that possible interferences are minimized, and physicians obtai...

Transcription factors organize into functional groups on the linear genome and in 3D chromatin

Transcription factors (TFs) and their binding sites have evolved to interact cooperatively or competitively with each other. Here we examine in detail, across multiple cell lines, such cooperation or competition among TFs both in sequential and spatial proximity (using chromatin conformation capture assays) on one hand, and based on both in vivo binding as well as TF binding motifs on the other. W...
