Forensic Physical Evidence Identification
- Evidence Collection at Crime Scenes：At crime scenes, dried bloodstains are common and crucial pieces of evidence. Dried bloodstain collection cards can effectively gather bloodstains for subsequent DNA analysis, which helps identify suspects or victims. For example, in violent crime scenes such as homicides and intentional injuries, the collection and analysis of dried bloodstains at the scene can establish a connection between the crime scene and the suspect or victim.
- Investigation of Sexual Assault Cases：In sexual assault cases, the dried bloodstains remaining on the victim’s body are of great significance for solving the case. Dried bloodstain collection cards can be used to collect these bloodstains and detect whether they contain the suspect’s DNA, providing strong evidence support for the fair trial of the case.
- Identification of Victims in Disaster Accidents：After large – scale disasters (such as earthquakes, fires, plane crashes, etc.), the bodies of the victims may have dried bloodstains due to various factors. Dried bloodstain collection cards can be used to collect these bloodstains for DNA identification, helping to identify the identities of the victims and providing key information for subsequent rehabilitation work.
Medical Testing and Diagnosis
- Screening for Hereditary Diseases：For some hereditary diseases, such as thalassemia and cystic fibrosis, dried bloodstain collection cards can be used to collect neonatal heel blood or other small amounts of blood samples. These samples can be subjected to genetic testing to determine whether the baby carries disease – causing genes, enabling early diagnosis and intervention.
- Detection of Blood – borne Diseases：In the detection of blood – borne diseases (such as AIDS, hepatitis B, hepatitis C, etc.), dried bloodstain collection cards can collect a small amount of blood for the detection of virus markers. This method is particularly convenient for people who are difficult to collect a large amount of blood (such as infants and those with difficult venous puncture), contributing to the early detection and control of diseases.
- Monitoring of Drug Concentration：During the clinical drug treatment process, it is necessary to monitor the drug concentration in the patient’s blood to adjust the treatment plan. Dried bloodstain collection cards can collect the patient’s dried bloodstains to detect the content of drug components and their metabolites, providing data support for precision medicine.
Biomedical Research
- Human Genetics Research：Researchers can use dried bloodstain collection cards to collect blood samples from different individuals and ethnic groups for studying human genetic diversity, gene evolution, and the association between genes and diseases. By analyzing the DNA in these samples, a better understanding of human genetic characteristics and the genetic basis of diseases can be achieved.
- Research on the Pathogenesis of Blood Diseases：In the research of blood diseases (such as leukemia, aplastic anemia, etc.), dried bloodstain collection cards can be used to collect blood samples from patients. Analyzing the morphology of blood cells and gene expression in these samples helps to reveal the pathogenesis of these diseases, providing a theoretical basis for the development of new treatment methods.
- Drug Research and Development Trials：During the drug research and development process, dried bloodstain collection cards can be used to collect blood samples from experimental animals or volunteers in clinical trials. By detecting drug – related indicators in the blood samples, the efficacy, safety, and pharmacokinetic characteristics of the drug can be evaluated, providing data support for the optimization and marketing of the drug.
Paternity Testing
- Resolution of Family Disputes：In family disputes involving paternity disputes, dried bloodstain collection cards can collect blood samples from parents and children. Through DNA comparison, the paternity relationship can be determined. This non – invasive (compared to traditional blood collection methods) sample collection method is more acceptable and can provide accurate identification results, helping to resolve family conflicts.
- Immigration and Household Registration Management：In the process of immigration and household registration management, paternity testing is sometimes required. Dried bloodstain collection cards can conveniently collect blood samples from relevant personnel, providing reliable evidence support for legal immigration and household registration.
