Blood Cholesterol Concentration Measured by CR3000: Fingerstick versus Venous Sampling

Q: What are the key findings of this study?

Capillary blood sampling for total cholesterol using the CR3000 system yielded similar results to venous sampling (168 mg/dL vs 164 mg/dL), with statistically similar variance (p<0.05).

Q: What is the clinical evidence from this study?

Study design: Observational. Intervention: Capillary blood sampling using CR3000 vs. Venous blood sampling using CR3000. Primary outcome: Total cholesterol concentration (p=<0.05).

Key result

Capillary point-of-care total cholesterol yields similar results to venous sampling.

P<0.05
n=21

Why the study?

The relationship between cholesterol determinations in venous and capillary samples using the CR3000 PoC system was not well established.

Does capillary blood sampling provide similar cholesterol measurements compared to venous sampling using the CR3000 PoC system in adult volunteers?

Population

21 unselected adult volunteers with no exclusion criteria

Comparison

Capillary blood sampling vs venous blood sampling for cholesterol measurement using CR3000

Implication

Comparable results support capillary sampling flexibility with CR3000; leaves open prospective validation before routine adoption.

Key Points

To evaluate the agreement between cholesterol concentrations measured from venous and capillary blood samples using the CR3000 point-of-care system.
Conducted a comparative evaluation in N=21 unselected adult volunteers without exclusion criteria.
Collected paired venous and capillary (fingerstick) whole blood samples and analyzed total cholesterol using the CR3000 point-of-care analyzer.
Mean cholesterol concentration was 164 mg/dL in venous samples compared to 168 mg/dL in capillary samples, representing a 2.87% difference.
Total variance between sampling techniques showed no significant difference (F = 1.199, upper critical value = 2.124, p < 0.05).

Sblendorio et al. (2008) reported an observational. Capillary blood sampling using CR3000 vs. Venous blood sampling using CR3000 was evaluated on Total cholesterol concentration (p=<0.05). Capillary blood sampling for total cholesterol using the CR3000 system yielded similar results to venous sampling (168 mg/dL vs 164 mg/dL), with statistically similar variance (p<0.05).
