Cell-free DNA blood collection tubes

Cell-free DNA blood collection tubes are mainly used for the following purposes:
Prenatal diagnosis: It is used to detect the genetic information of the fetus and assist in determining whether the fetus has chromosomal abnormalities and other problems.
Tumor detection: It can be used to detect tumor-related gene mutations to help early diagnosis of tumors, monitor tumor progression and evaluate treatment effects.
Disease monitoring: to monitor and evaluate certain diseases, such as autoimmune diseases.

The following are some of the diseases that can be detected by cell-free DNA blood sampling tubes:
Tumor diseases: such as lung cancer, breast cancer, colorectal cancer, and many other cancers.
Fetal chromosomal disorders: e.g. Down’s syndrome, etc.
Autoimmune diseases: such as systemic lupus erythematosus.

The principle of detection of cell-free DNA blood collection tubes is based on the following points:
Free DNA release: Cell-free DNA in the blood is released from the cells.
PCR Amplification: Specific DNA fragments are amplified using Polymerase Chain Reaction (PCR) technology to increase the sensitivity of the test.
Sequencing or specific assays: Sequencing of amplified DNA or the use of specific assays to identify and analyze genetic variants or features associated with disease.

Cell-free DNA blood collection tubes have some advantages over traditional DNA testing methods:
Non-invasive: only blood collection is required, which is less traumatic to the patient.
Early detection: Abnormalities can be detected at the early stage of the disease, which can help early diagnosis and treatment.
Convenience: easy sampling and relatively simple operation.
Repeatability: It can be performed several times, which is convenient for monitoring the progress of the disease.
Wide range of application: not only can be used for prenatal diagnosis, but also can be applied to the detection of a variety of diseases.
