Blood Sample Cards
Blood sample cards are designed for the collection, storage, and preservation of blood samples. They typically feature absorbent materials that allow for the controlled drying of blood, ensuring that the sample remains viable for future DNA analysis or other testing purposes. -
Saliva Collection Devices
Saliva collection devices are used to gather saliva samples for forensic or medical purposes. These devices are often made with specialized swabs or absorbent material that capture saliva from the mouth. They are commonly used in DNA analysis, drug testing, and paternity testing. -
How to Use Together
-
Step 1: Collect the blood sample using the appropriate collection tool (e.g., a collection pen or swab). Apply the sample to the blood sample card.
-
Step 2: Simultaneously or at a later stage, collect the saliva sample using the designated saliva collection device (e.g., a saliva swab or funnel).
-
Step 3: Store both the blood sample card and saliva collection device in secure and sterile conditions to prevent contamination and preserve the integrity of the samples.

Advantages of Combined Use
-
Versatility: Combining both blood and saliva samples allows for a broader range of forensic analyses, including DNA profiling and drug testing.
-
Efficiency: By collecting multiple samples simultaneously or in close proximity, investigators or healthcare professionals can streamline their sample collection process.
-
Enhanced Preservation: Both blood sample cards and saliva collection devices are designed to preserve biological samples for extended periods, ensuring that they remain viable for analysis.
-
Features
-
Non-invasive: Both blood sample cards and saliva collection devices are minimally invasive and easy to use.
-
Portable: These tools are portable and convenient for use in various settings, including fieldwork and lab environments.
-
Secure Storage: Both sample types are stored in ways that prevent contamination and maintain sample integrity.
Scope
This combined approach is widely used in forensic investigations, paternity testing, medical diagnostics, and research studies, where both blood and saliva samples are required for comprehensive analysis.
