The study found that self-collection of dried blood spots and other samples using at-home kits was a useful and cost-effective method for screening a large cohort for sexually transmitted infections outside a clinic. This demonstrates the feasibility of decentralised, patient-centric sampling for population-level infectious disease surveillance.

Although most kidney transplant recipients successfully collected capillary blood samples at home, haemolysis and transport conditions affected analyte stability. Agreement with venous sampling was acceptable for haemoglobin and creatinine, but potassium and haematocrit exceeded total allowable error limits.

This developer study reports that a self-collection kit interfacing with a BD Microtainer produced RNA of sufficient quality and yield for transcriptomic analysis in a pilot group and a longitudinal rheumatology cohort. Most participants found the device easy to use, supporting its utility for decentralised blood sampling.

A head-to-head of four upper-arm capillary devices, including TAP Micro Select, versus fingerstick and venous: experience and performance varied by device with none clearly superior, while analyte correlations with venous were similar across all.

A vacuum-assisted upper-arm device collected a mean 538 µL and met the volume target in 85.5% of cases; 17 of 19 analytes met CLIA agreement with venous, with pain lower than fingerstick.

A study of decentralised patient-centric microsampling found that 82% of untrained participants, 47 of 57, successfully self-collected acceptable fingerstick blood in Microtainer tubes. All 46 tested samples yielded accurate HIV viral suppression results compared to venipuncture, though this remote monitoring approach is limited to US courier services and temperature conditions.

A prospective study of 109 subjects found that 250 μl capillary whole blood microsampling is stable for five hours in a microtainer. This patient-centric, decentralised method successfully detected most HCV genotypes at defined limits using the Xpert HCV test on the GeneXpert Xpress system and the cobas HCV platform.

Plasma total carbon dioxide concentrations were significantly lower in BD Microtainers compared to standard vacutainers, with reductions driven by low sample volume and transport delays rather than brief air exposure. These findings indicate that microtainers must be filled completely and analysed rapidly to maintain accuracy for this analyte.

This study evaluated the repeatability of a point-of-care G6PD test using capillary blood collected via fingerprick and BD Microtainers, finding that modified sample application methods reduced variability in laboratory and field settings.

TAP II capillary serum, both professionally collected and self-collected, correlated with venous serum at R > 0.9 for eight analytes including ALT, AST, cholesterol, HDL and triglycerides. Creatinine correlated acceptably but carried a consistent negative bias, and carbon dioxide, potassium and albumin did not reach acceptable agreement: the useful reading is that the panel has to be validated, not the device alone.

Fingerstick blood self-collected into BD Microtainer tubes and posted at ambient temperature for 24 h agreed acceptably with paired serum for 11 of 12 analytes, HbA1c, lipids, creatinine, urea, urate, liver enzymes and total protein, with only AST falling outside limits.

Capillary blood collected in BD Microtainer tubes remained stable for up to 12 days at room temperature and gave accurate HbA1c results when posted back, with high return rates and patient willingness to reuse the system.

Fingerstick plasma collected in Microtainer tubes showed 100% concordance with matched venous plasma on the Abbott ARCHITECT SARS-CoV-2 IgG assay, n=109. Fingerstick dried blood spots found high concordance with venous samples, n=61, supporting these microsampling methods for decentralised serology.

The study found that HIV-1 viral load testing using fingerstick blood collected in BD Microtainer tubes showed high correlation, R² ≥0.980, with standard venous assays, supporting decentralised patient-centric microsampling. The authors note the limitation that testing was performed at a single laboratory site.

A US survey of 3,400 adults aged 62 to 90 collected up to 15 biomeasures at home, including saliva, dried blood spots and urine, with Salivette and Oragene among the devices used, which shows that several patient-centric sampling methods can run together in home-based research.
