Sampling Area: The card typically features multiple pre-printed circles (usually 3-5) to indicate the blood drop location. Each circle must be completely saturated with blood.

Information Area: This area is blank for filling in or pasting basic patient information, such as name, serial number, date of birth, and sampling date and time. This is crucial for sample traceability.

Drying and Anti-Contamination Design: The dried blood spot can be placed in a dedicated plastic bag or envelope with a desiccant to prevent moisture and ensure sample stability during transport.

Main Uses of Blood Collection Cards
Blood collection cards have a wide range of applications, particularly in the following areas:

Newborn Disease Screening: This is the most widely known use. Within a few days of birth, a newborn’s blood is collected via a heel prick onto a blood sampling card. The blood is then sent to a specialized laboratory for testing to screen for dozens of inherited metabolic diseases, including phenylketonuria, hypothyroidism, and congenital adrenal hyperplasia.

Epidemiological Surveys and Disease Surveillance: Blood sampling cards are ideal tools for large-scale population studies (such as epidemiological surveys of HIV, hepatitis, and malaria) due to their ease of collection, transportation, and storage.

Therapeutic Drug Monitoring: They are used to monitor drug concentrations in patients’ blood to assess efficacy and adjust dosages.

Biomarker Testing: They are used to detect hormones, antibodies, and viral nucleic acids (such as HIV DNA/RNA).

Forensic Medicine: They are used for DNA analysis and personal identification.

Pet Health Testing: Blood sampling cards are also commonly used in the veterinary field to test pets for infectious diseases.

Advantages

Minimally Invasive and Simple: Requiring only a fingertip or heel prick, no venous blood sampling is required. This procedure is minimally invasive to the patient (especially infants), simple to perform, and can be performed by trained non-specialists.

Easy to Transport and Store: Dried blood spots contain no liquid and are not prone to leakage. They are generally considered a low-risk biosafety material and can be shipped via regular mail. They take up little storage space and can be stored long-term at room temperature or frozen at -20°C.

Good Stability: Many analytes (such as antibodies and DNA) in dried blood spots are quite stable at room temperature and are not easily degraded.

Low Cost: The card itself is low-cost and significantly reduces the costs of blood collection tubes, centrifugation, and frozen shipping.

Disadvantages and Limitations: Limited Sample Volume: Each blood spot provides a small amount of serum/plasma, limiting the ability to perform repeat tests or multiple tests.

Blood Cell Interference: Whole blood samples contain blood cells, which may interfere with certain test methods.

Blood Spot Quality Affects Results: Insufficient blood volume, uneven penetration, contamination, or insufficient drying can significantly affect the accuracy of test results.

Standardization Challenges: Accurate quantitative analysis is more challenging than with liquid blood samples.

Basic Procedure
Preparation: Verify patient information and prepare the blood collection card, lancet, alcohol pad, etc.

Blood Collection: Clean the blood collection site (such as a fingertip or heel), prick the skin with the lancet, and wipe away the first drop of blood.

Blood Dropping: Allow the blood to form a droplet naturally. Gently touch the filter paper on the blood collection card, allowing it to absorb and completely fill a circle. Avoid repeated drops or touching the filter paper surface.

Drying: Place the blood collection card horizontally on a drying rack and air dry at room temperature for at least 3-4 hours, avoiding direct sunlight and heat.

Shipping: After drying, place the blood collection card in a dedicated moisture-proof bag and mail it to the testing laboratory along with the application form.

These chemically treated filter papers have become an indispensable tool across various scientific and medical fields, offering unparalleled convenience, reliability, and efficiency.​

Working Principle​
At the core of FTA Cards’ functionality lies their unique composition of cotton-based cellulose paper impregnated with specific chemicals. When a biological sample, such as blood, saliva, or tissue cells, is applied to the FTA Card, these chemicals initiate a series of reactions. They cause cell lysis and protein denaturation, while simultaneously immobilizing nucleic acids within the card’s matrix. This process effectively protects the nucleic acids from degradation by ultraviolet light, oxidation, and nucleases, ensuring their integrity for downstream analysis.​

Usage​
Using FTA Cards is a straightforward process. Simply apply the biological sample to the designated area on the card. Once the sample dries, the nucleic acids are stably bound to the card. For subsequent nucleic acid analysis, a small section of the card containing the sample is cut out and subjected to a simple purification procedure. The purified nucleic acids can then be used in a wide range of downstream experiments, including PCR, sequencing, and SNP analysis.​

Types​
FTA Cards come in various types to meet different sample collection and storage needs. The FTA Classic Card features 4 sample areas and can store up to 500µl of whole blood or 100µl of plant homogenate. The FTA Mini Card has 2 sample areas and can hold up to 250µl of whole blood or 50µl of plant homogenate. The FTA Micro Card, with 1 sample area, is designed to store up to 125µl of whole blood or 25µl of plant homogenate. The FTA GeneCard, equipped with 3 sample areas, is compatible with a variety of automated liquid handling systems. Finally, the FTA Elute Micro Card, which has 4 sample areas, is ideal for applications such as STR analysis, sequencing, and real-time PCR.​

Advantages​
One of the most significant advantages of FTA Cards is their ability to store and transport biological samples at room temperature. This eliminates the need for costly and cumbersome cold storage facilities, making sample handling more convenient and cost-effective. Additionally, samples stored on FTA Cards can be preserved for extended periods. Genomic DNA on FTA Cards can remain viable for PCR amplification for over 17.5 years at room temperature. FTA Cards also rapidly inactivate infectious pathogens in samples, reducing the risk of disease transmission and often eliminating the need for import licenses. Moreover, their simple operation – just drop the sample on the card and let it dry – makes them accessible to users with varying levels of technical expertise.​
Applications​
In the field of molecular biology, FTA Cards are widely used for whole genome sequencing, genomic research, and plasmid screening. In forensic science, they play a crucial role in STR analysis, animal identification, and transgenic identification.

Oral cell collection cards often incorporate specific indicator types to enhance the sampling process and ensure accurate sample collection. These indicators play a crucial role in providing visual cues about the presence and adequacy of the collected sample.​

Color – Changing Indicators​

• Most Common Type: A prevalent indicator type is the color – changing one. For instance, many high – quality oral cell collection cards, such as the ones used in both research and forensic applications, are designed with a color – changing mechanism. When the card comes into contact with saliva or oral cells, a chemical reaction occurs within the indicator area.​

• Example of Color Shift: In some cards, the initial color of the indicator region is pink. As soon as the biological sample, which contains saliva or oral mucosal cells, makes contact with this area, the color rapidly changes to white. This color transition is highly visible and serves as an immediate confirmation that the sample has been successfully deposited on the card. For example, the Huachenyang oral cell collection card uses this pink – to – white color – changing system. This clear visual signal is beneficial for users, especially in scenarios where quick and accurate sample collection is essential, like in large – scale genetic screening programs or forensic investigations where multiple samples need to be processed in a short time.​

Fluorescent Indicators​

• Function in Low – Light Conditions: Fluorescent indicators are also utilized in certain specialized oral cell collection cards. These indicators emit a fluorescent glow when exposed to a specific wavelength of light after the sample has been applied. This type of indicator is particularly useful in situations where traditional color – changing indicators may be difficult to observe, such as in low – light environments or when the sample volume is extremely small.​

• Advantages in Research Settings: In research laboratories, fluorescent indicators can be used to precisely locate and quantify the amount of oral cells collected. By using fluorescence microscopy or other fluorescence – detecting equipment, researchers can accurately analyze the distribution and concentration of the cells on the collection card. This level of precision is valuable for studies that require detailed cellular analysis, such as those focused on understanding the genetic makeup of specific oral cell populations or investigating the relationship between oral microbiota and certain diseases.​

pH – Sensitive Indicators​

• Principle of Operation: pH – sensitive indicators work based on the change in the pH value of the sample. Oral fluids have a characteristic pH range, and when they interact with the indicator on the collection card, a color change occurs due to the pH – dependent chemical properties of the indicator. For example, an indicator might change from one color at a neutral pH to another color when the pH of the sample is slightly acidic, which is typical of oral fluids.​

• Use in Quality Control: This type of indicator can also serve as a form of quality control. If the pH – sensitive indicator does not show the expected color change, it could indicate that the sample is not a proper oral fluid sample (e.g., it may be contaminated with other substances that alter the pH) or that there is an issue with the collection card itself. This helps in ensuring that only valid samples are further processed for DNA extraction and analysis.
