Sažetak
BACKGROUND-AIM: Point-of-care testing (POCT) comprises diagnostic testing usually performed by non-laboratory personnel at the site of the patient (i.e. hospital wards or at home). The comparability of results obtained from left hand (L) vs. right hand (R) capillary sampling samples using POCT is implied. Our aim was to test this hypothesis, i.e. to test if results obtained from L and R hand capillary samples by using a POCT device were comparable. METHODS: Paired capillary samples were taken simultaneously from L and R middle fingers of 21 healthy participants using Greiner bio-one miniCollect safety lancets with puncture depth of 2.00 mm. A volume of 200 μL of capillary blood from each finger was collected using lithium- heparinized Minivette POCT (Sarstedt, Nümbrecht, Germany). Testing was performed using Abbott i-STAT Alinity (Abbott, Abbott Park, USA) POCT analyser and Na, K, Cl, iCa, glucose, urea, creatinine, haematocrit, haemoglobin, pH, PCO2, PO2, TCO2, HCO3-, base excess (BE), sO2, lactate were measured. Statistical analysis was performed using MedCalc statistical software (Ostend, Belgium). Mean biases obtained from L vs. R were compared to CROQALM criteria for respective parameters. RESULTS: No statistical or clinical difference in results obtained after sampling from L and R was found. Calculated biases for each parameter analysed were lower than the criteria previously defined. The biases expressed as mean bias (corresponding criteria) were as follows: pH 0.04% (1%), pCO2 - 0.24% (8%), pO2 2.00% (8%), lactate -4.35% (16%), Na 0.30% (3%), K 1.65% (6%), Cl – 0.15% (4%), urea 0.88% (8%), creatinine 1.19% (9%), glucose - 0.87% (7%), iCa 1.79% (4%), Hct 1.25% (5%), Hb 1.22 (5%). CONCLUSIONS: Results obtained from L and R hand capillary samples using a POCT device were comparable. Thus, capillary sampling might be performed from either hand, interchangeably.
