Insights

Serum carbohydrate-deficient transferrin (CDT) levels are unaffected by blood collection tube type. This study found no significant differences in CDT determination across four common blood collection tube materials, ensuring reliable testing regardless of tube choice.

Area of Science:

  • Clinical Chemistry
  • Laboratory Medicine
  • Biochemistry

Background:

  • Carbohydrate-deficient transferrin (CDT) is a biomarker used in clinical diagnostics.
  • Accurate CDT determination is crucial for reliable patient assessment.
  • The choice of blood collection tube can potentially influence laboratory test results.

Purpose of the Study:

  • To investigate the impact of different blood collection tube types on serum carbohydrate-deficient transferrin (CDT) measurements.
  • To evaluate the compatibility of various tube materials with CDT testing using the CDTect method.

Main Methods:

  • Serum samples from 58 individuals were analyzed.
  • Four types of blood collection tubes were tested: glass, plastic (no additive), plastic (serum accelerator), and plastic (serum/gel accelerator).
  • Serum isolation and CDT determination were performed using the CDTect method.
  • Passing and Bablok regression analysis was employed to compare results.

Main Results:

  • No statistically significant differences were observed in CDT concentrations across the four tested blood collection tube types.
  • The results indicate that serum isolation in glass, neutral plastic, serum plastic, or serum/gel plastic tubes does not affect CDT determination.
  • The CDTect method demonstrated robustness across different collection systems.

Conclusions:

  • The type of blood collection tube used for serum isolation does not impact the accuracy of carbohydrate-deficient transferrin (CDT) determination.
  • Clinicians and laboratory professionals can confidently use various common blood collection tubes for CDT testing.
  • Standardization of CDT testing is supported across different pre-analytical sample handling procedures.

Membrane Carbohydrates01:30

Membrane Carbohydrates

The plasma membrane is a dynamic barrier composed of lipids, proteins, and carbohydrates. It is the epicenter of many cellular processes required for cell growth and survival. Carbohydrates have unique structural and chemical properties that help the plasma membrane to carry out its functions effectively.
Membrane carbohydrates do not have any hydrophobic region and are exclusively located on the cell's outer surface. The addition of sugar molecules or glycosylation of proteins happens in...
Glucose Transporters01:27

Glucose Transporters

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
Overview Of Cell Separation And Isolation01:20

Overview Of Cell Separation And Isolation

Cell separation was first achieved in 1964 by S. H. Seal, who separated large tumor cells from the smaller blood cells using filtration. Two years later, Pohl and Hawk performed experiments on how cells respond differently to a nonuniform electric field based on the cell type. Such observations were the inception of cell separation methods, which allow isolating a single cell type from a heterogeneous sample.
Overview of Carbohydrate Metabolism01:19

Overview of Carbohydrate Metabolism

Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...
Carbohydrate Absorption01:25

Carbohydrate Absorption

Carbohydrates are essential macronutrients that serve as the body's primary energy source. Their digestion begins in the mouth, where salivary amylase partially breaks down complex carbohydrates such as starch into smaller oligosaccharides. This mechanical and enzymatic activity prepares carbohydrates for further processing in the gastrointestinal tract.
After being swallowed, the partially digested carbohydrates mix with gastric secretions in the stomach. However, the acidic environment...
