Comparación de un hemoglobinómetro portátil (Verio Q Red) con los resultados del laboratorio clínico en la práctica clínica habitual

Objective

To analyze the concordance between a hemoglobinometer with capillary blood sample and the clinical laboratory with a venous blood sample.

Design

Cross-sectional concordance study.

Location

Care Centre Primary Bufalà-Canyet Primary and Care Centre Primary Dalt la Vila Primary Care Center, Badalona, Barcelona.

Participants

Random selection of participants who attended routine blood tests. Over 18 years old. No abandonment or loss was obtained.

Main interventions and measurements

Sex, age, and reason for the blood test were collected from the medical history. Venous blood is drawn, and simultaneously, capillary blood is collected.

Results

120 individuals are included, with an average age of 58.9 years. The Bland-Almant graph showed differences within the confidence intervals for hemoglobin and hematocrit. The mean differences between the values of the Verio Q Red hemoglobinometer and those of the clinical laboratory were −0.42 mg/dl for hemoglobin and −1.25% for hematocrit. The intraclass correlation coefficient showed excellent correlation for hemoglobin and hematocrit between the Verio Q Red hemoglobinometer and the clinical laboratory. Pearson's correlation for hemoglobin was 0.737 and for hematocrit 0.787.

Conclusions

The Verio Q hemoglobinometer is a valid tool for the early diagnosis of anemias and can be very useful in primary care consultations.
