“…2 Aggregating the results quoted in Cembrowski and Füzéry's correspondence describing visible hemolysis in shallow lanced samples from a previously unpublished study, 20 out of 141 "shallow" samples showed visible hemolysis after spinning. 1 Why was the focus of our original correspondence on deep lancing? This was because its context related to the recent paper by Klonoff et al, describing a blood glucose monitor system surveillance protocol.…”

“…We are responding to the thoughtful letter by Cembrowski and Füzéry, "Deep Lancing or Over Manipulation," in this issue of the Journal of Diabetes Science and Technology, 1 which was written in response to our initial letter, "How Much Hemolysis Is Acceptable When Undertaking Deep Lancing for Finger Stick Derived Capillary Plasma Glucose Measurement?" 2 The purpose of our initial correspondence was to encourage open sharing of data and insights on the mechanisms and effects of hemolysis, in relation to capillary sample acquisition for plasma glucose measurement.…”

“…2 We are therefore pleased that Cembrowski and Füzéry provided new data and also progressed this discussion. 1 Hemolysis appears to be common when collecting capillary "finger stick" samples: We reported hemolysis indices from 42 participants obtained during a previous study. 3 Standardized procedures for capillary sample collection were used throughout this study.…”

Validity and reliability of capillary vs. Venous blood for the assessment of haemoglobin mass and intravascular volumes

Objectives: Haemoglobin mass (Hbmass) assessment with the carbon monoxide rebreathing method is a more accurate estimate than other measures of oxygen-carrying capacity. Blood may be collected by several means and differences in the measured variables may exist as a result. The present study assessed the validity and reliability of calculated Hbmass and intravascular volumes obtained from capillary blood (CAP) when compared to venous blood (VEN) draws.Methods: Twenty-two adults performed a carbon monoxide rebreathing procedure with paired VEN and CAP draws at baseline, pre-rebreathing and post-rebreathing (POST). Thirteen of these participants performed this protocol on two occasions to assess the data reliability from both blood sampling sites. In a second experiment, 14 adults performed a 20-min seated and a 20-min supine rest to assess for the effect of posture on haematological parameters.Results: Haemoglobin mass (CAP = 948.8 ± 156.8 g; VEN = 943.4 ± 157.3 g, p = 0.108) and intravascular volume (CAP = 6.5 ± 1 L; VEN = 6.5 ± 0.9 L, p = 0.752) were statistically indifferent, had low bias (Hbmass bias = 14.45 ± 40.42 g, LoA -64.78 g—93.67 g) and were highly correlated between sampling techniques. Reliability analysis demonstrated no difference in the mean change in variables calculated from both sampling sites and good to excellent intraclass correlation coefficients (>0.700), however, typical measurement error was larger in variables measured using CAP (VEN Hbmass TE% = 2.1%, CAP Hbmass TE% = 5.5%). The results indicate that a supine rest prior to the rebreathing protocol would have a significant effect on haemoglobin concentration and haematocrit values compared to a seated rest, with no effect on carboxyhaemoglobin %.Conclusion: The present study demonstrates that CAP and VEN were comparable for the calculation of Hbmass and intravascular volumes in terms of accuracy. However, reduced reliability and increased error in the CAP variables indicates that there are methodological considerations to address when deciding which blood drawing technique to utilise. To reduce this CAP error, increased replicate analyses are required.
