Principles and Applications of Huachen Yang Dried Blood Spot Collection Cards

Huachen Yang dried blood spot collection cards are tools used for collecting and preserving blood samples, widely applied in medical testing, disease screening, and scientific research. They are designed to collect blood conveniently and ensure sample stability during transport and storage.

Principle

The working principle of dried blood spot collection cards is based on the drying and fixation of blood. During the collection process, users typically use a needle or other non-invasive method to draw a small amount of blood from the fingertip or earlobe. The blood is then placed on a specially designed collection card, which has absorbent properties that rapidly absorb the blood and form a dried spot on the surface. This process effectively prevents degradation of the blood sample in its liquid state, ensuring reliability in subsequent analyses.

The materials used in Huachen Yang dried blood spot collection cards are usually biocompatible, avoiding interference with the sample components. These materials do not release harmful substances during drying, thus maintaining the integrity of the sample. Furthermore, the card’s surface is specially treated to enhance blood fixation efficiency, making samples less prone to deterioration during long-term storage.

Applications

The applications of Huachen Yang dried blood spot collection cards are extensive, primarily including the following areas:

1. Disease Screening: Dried blood spot collection cards are widely used for screening infectious diseases, metabolic disorders, and genetic conditions. For instance, initial screenings for HIV, hepatitis B, and hepatitis C can be conducted using these cards. This method is especially useful in resource-limited areas, allowing simple testing without the need for specialized laboratories.
2. Drug Monitoring: In the context of drug therapy, healthcare providers can use dried blood spot collection cards to monitor patients’ drug concentrations and assess treatment efficacy. This monitoring is particularly important for chronic disease patients, helping doctors adjust medication regimens to ensure patient safety.
3. Scientific Research: In medical and biological research, dried blood spot collection cards serve as sample collection tools, facilitating researchers in obtaining necessary biological samples. This method not only simplifies sample handling but also improves research efficiency.
4. Blood Storage: For long-term monitoring of certain diseases, dried blood spot collection cards provide a convenient blood storage solution. By drying the samples, they can be preserved at room temperature, allowing for easy testing and analysis in the future.

In summary, Huachen Yang dried blood spot collection cards, with their convenience, efficiency, and safety, have become essential tools in modern medical testing and research.
