Maximizing microsampling: measurement of comprehensive metabolic and lipid panels using a novel capillary blood collection device

Collier et al.

The finding, in our words

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.

A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.

    Self-collected capillary blood samples posted by standard mail showed high concordance with couriered venous samples for HbA1c, creatinine and lipid parameters, supporting their use for remote monitoring in diabetes management and screening.

    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.

    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.

    Plasma lipidomes from self-collected upper-arm capillary blood were statistically indistinguishable from paired venous plasma, most classes at r=0.95–0.99, validating at-home capillary self-collection for lipidomics.

    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.
