Point of care rapid diagnostic tests (POC-RDT) for Hepatitis C virus (HCV), Human Immunodeficiency virus (HIV), and Hepatitis B virus (HBV) play a crucial role in non-clinical outreach settings, providing immediate results and facilitating diagnosis for high-risk populations. These tests are particularly important for vulnerable groups such as drug users, migrants, and homeless individuals, who may face challenges accessing traditional healthcare facilities. This study aimed to compare the accuracy of POC-RDT with laboratory conventional tests to assess the feasibility and effectiveness of using rapid tests in outreach settings. Get ready for some eye-opening insights!
The study involved 301 vulnerable individuals who were recruited at a mobile screening unit in outreach settings in Madrid. These individuals represented high-risk populations that might have limited access to healthcare. Fingerprick whole blood capillary samples were collected and tested using three different POC-RDTs: SD BIOLINE HCV for HCV, Determine HIV Early Detect for HIV, and Determine HBsAg 2 for HBV. The results were then compared with the reference assays, namely LIAISON XL HCV, HIV and Murex-HBsAg-Quant, used in laboratory conventional tests.
The results of the study demonstrated high sensitivity and specificity for the POC-RDTs. For HCV, the SD-BIOLINE-HCV test showed a resolved sensitivity of 98.8% and a resolved specificity of 100.0%. Similarly, the Determine HIV Early Detect test exhibited 100% sensitivity and 100% specificity. For HBV, the Determine HBsAg 2 test achieved a resolved sensitivity of 66.7% and a resolved specificity of 100.0%. Although the number of subjects with confirmed positive results for HBsAg was relatively low, the test demonstrated 100% sensitivity for standard concentrations of 0.125 IU/mL or higher.
Apart from accuracy, user satisfaction and feasibility were also evaluated through a questionnaire. The feedback from the subjects was overwhelmingly positive, indicating that the POC-RDT fingerprick blood collection method was well-received. This aspect is crucial, as it ensures that the testing process is non-invasive and comfortable for the individuals being screened.
The study findings suggest that POC-RDTs hold tremendous promise in outreach settings and among vulnerable high-risk populations. With their high accuracy and ease of use, these rapid tests can significantly improve access to early diagnosis and timely treatment for infectious diseases like HCV, HIV, and HBV.
