Saliva sample collection kits are tools used for the collection, preservation, and transportation of saliva samples

They can be applied in multiple fields, including medical diagnosis, disease monitoring, drug research and development, genetic testing, and oral health assessment. Here are the specific applications:

Medical Diagnosis

• Detection of Infectious Diseases
  By detecting the nucleic acids or antigens of viruses, bacteria, and other pathogens in saliva, it can diagnose infections such as influenza virus, COVID – 19 virus, Epstein – Barr virus, and Helicobacter pylori. For example, during the COVID – 19 pandemic, saliva samples were used for nucleic acid testing. This method is convenient, non – invasive, and highly acceptable to patients.
• Diagnosis of Autoimmune Diseases
  Certain autoimmune diseases can lead to the presence of specific autoantibodies and other markers in saliva. Detecting these substances helps in the diagnosis of diseases. For instance, in patients with Sjogren’s syndrome, autoantibodies such as anti – SSA and anti – SSB may be present in saliva.
• Diagnosis of Genetic Diseases
  Gene mutations related to some genetic diseases can be detected in saliva cells. For single – gene genetic diseases like cystic fibrosis, collecting saliva for genetic testing can assist in disease diagnosis and genetic counseling.

Disease Monitoring

• Tumor Monitoring
  Saliva may contain biomarkers related to tumors, such as DNA, RNA, and proteins released by tumor cells. By regularly collecting saliva samples and monitoring the changes in these biomarkers, it can be used for early tumor screening, evaluation of treatment effectiveness, and recurrence monitoring. For example, in patients with oral cancer, lung cancer, etc., specific gene mutations or abnormally expressed proteins may be present in saliva.
• Management of Chronic Diseases
  For chronic diseases such as diabetes and cardiovascular diseases, certain components in saliva, such as glucose and inflammatory factors, can reflect the status and progression of the disease. Regularly detecting these indicators in saliva helps doctors adjust treatment plans and achieve precise disease management.

Drug Research and Development

• Evaluation of Drug Efficacy
  In clinical drug trials, collecting saliva samples to detect drug metabolites or relevant biomarkers can assess the absorption, distribution, metabolism, and excretion of drugs in the body, as well as the impact of drugs on disease – related indicators. This provides a basis for evaluating drug efficacy.
• Monitoring of Adverse Drug Reactions
  Some drugs may cause oral or systemic adverse reactions. By analyzing the changes in relevant indicators in saliva, signs of adverse drug reactions can be detected at an early stage. For example, some drugs may cause changes in enzyme activity or the appearance of abnormal metabolites in saliva, which helps to adjust the medication plan in a timely manner and ensure the safety of patients’ medication.

Genetic Testing

• Mapping of Individual Genetic Profiles
  Oral epithelial cells in saliva contain the complete human genomic DNA. Using saliva samples, whole – genome sequencing or genotyping can be carried out to map an individual’s genetic profile, understand an individual’s genetic characteristics, including genetic susceptibility to certain diseases and drug – response genes. This provides a basis for personalized medicine.
• Kinship Identification
  In forensic medicine and paternity testing, the DNA in saliva samples can be used for genetic testing methods such as STR typing. By comparing genetic loci, the kinship between individuals can be determined. This method has the advantages of being non – invasive and convenient.

Oral Health Assessment

• Diagnosis of Oral Diseases
  It can be used to detect the microbial communities of bacteria, fungi, etc. in saliva, analyze the ecological balance of the oral microbiota, and assist in the diagnosis of oral diseases such as periodontitis and dental caries. It can also detect inflammatory factors, enzymes, and other components in saliva to evaluate the oral inflammatory state.
• Guidance for Oral Health Care
  By analyzing the components in saliva, such as pH value, buffering capacity, calcium and phosphorus content, etc., the physiological state of an individual’s oral cavity can be understood, providing a basis for formulating personalized oral health care plans. For example, it can guide the correct way of brushing teeth and the selection of appropriate oral care products.
