Product Description

Cell-Free DNA (cfDNA) is a biological molecule present in the bloodstream, typically consisting of fragments of nucleic acids, such as DNA. This DNA usually originates from the natural breakdown of cells, but in certain situations, such as tumor growth or when the body is in an inflamed state, its concentration can increase.

In the medical field, cfDNA in the bloodstream holds significant clinical applications. Here are some key areas of application:

Tumor Analysis:
cfDNA analysis can be used for early tumor detection, monitoring tumor progression, and predicting responses to tumor treatments. This approach is known as liquid biopsy, allowing the detection of tumor-specific genetic variations or mutations from a blood sample.

Non-Tumor Disease Analysis:
cfDNA analysis is also useful for detecting non-tumor diseases, such as autoimmune disorders. By examining the immune system's responses and levels of cytokines in the blood, it can aid in diagnosing and monitoring these conditions.

Prenatal Diagnosis:
Testing fetal cfDNA in the maternal bloodstream is employed in prenatal diagnosis, including screening for genetic disorders such as Down syndrome in the fetus.

Inflammation Detection:
The concentration of cfDNA increases in the bloodstream when the body experiences inflammation. Thus, it can also be used to detect and monitor inflammatory diseases such as rheumatoid arthritis or inflammatory bowel disease.

In summary, cfDNA analysis provides a non-invasive method for diagnosing and monitoring numerous clinical conditions, offering valuable insights into the state of health from a blood sample. Maintaining the stability and integrity of blood samples is crucial to ensuring accurate test results, underscoring the importance of selecting and handling storage containers effectively.

Product Performance

Fig.1 Testing with Different Preservatives

The experiment tested the ability of the cfDNA blood collection tube to preserve blood samples at room temperature for an extended period. The results showed that the cfDNA blood collection tube from USH effectively maintained the stability of white blood cells in the blood samples for up to 7 days, and compared to other brands, the white blood cell viability was good.

This demonstrates that the cfDNA blood collection tube can keep blood samples stable outside the body. When the number of deteriorated and ruptured white blood cells is reduced, it helps prevent interference in DNA testing caused by the release of genomic DNA from ruptured blood cells.
The cfDNA blood collection tube allows blood samples to remain stable at room temperature, providing higher-quality DNA specimens for testing and improving the accuracy of DNA testing.
