Epidermal Differentiation Genes of the Common Wall Lizard Encode Proteins with Extremely Biased Amino Acid Contents

The epidermal differentiation complex (EDC) is a cluster of genes that code for protein components of cornified cells on the skin surface of amniotes. Squamates are the most species-rich clade of reptiles with skin adaptations to many different environments. As the genetic regulation of the skin epidermis and its evolution has been characterized for only a few species so far, we aimed to determine...

Unexpected abnormal coagulation test results in a 2-year-old child

Rejection of the sample with repeated blood withdrawal is always an unwanted consequence of sample nonconformity and preanalytical errors, especially in the most vulnerable population – children. Here is presented a case with unexpected abnormal coagulation test results in a 2-yearold child with no previously documented coagulation disorder. Child is planned for tympanostomy tubes removal unde...

Affordable Biologics for All

To paraphrase something that Mark Twain is alleged to have said, “Everybody talks about drug prices, but nobody does anything about them.” The last part of the paraphrase is not quite accurate, but to date, none of the major federal proposals to lower drug prices have been enacted, and state legislation, such as the California Preserving Access to Affordable Drugs Act, is under legal challenge...

Diagnostic role of urine human epididymis protein 4 in ovarian cancer

Urine human epididymis protein 4 (HE4) is a promising, non-invasive tumor marker for ovarian cancer (OC), offering advantages in early detection and monitoring. Studies show urine HE4 concentrations are higher than serum levels, with comparable sensitivity and specificity for detecting OC. It can aid in the differential diagnosis, monitor chemotherapy response, and track disease recurrence. Howeve...

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...
