2. Accuracy of the HumaSensplus point-of-care uric acid meter using capillary blood obtained by fingertip puncture (PubMed)

Accuracy of the HumaSensplus point-of-care uric acid meter using capillary blood obtained by fingertip puncture The uric acid (UA) level in patients with gout is a key factor in disease management and is typically measured in the laboratory using plasma samples obtained after venous puncture. This study aimed to assess the reliability of immediate UA measurement with capillary blood samples obtained by fingertip puncture with the HumaSensplus point-of-care meter.UA levels were measured using (...) both the HumaSensplus meter in the clinic and the routine plasma UA method in the biochemistry laboratory of 238 consenting diabetic patients. HumaSensplus capillary and routine plasma UA measurements were compared by linear regression, Bland-Altman plots, intraclass correlation coefficient (ICC), and Lin's concordance coefficient. Values outside the dynamic range of the meter, low (LO) or high (HI), were analyzed separately. The best capillary UA thresholds for detecting hyperuricemia were

6. Correlation and Interchangeability of Venous and Capillary Blood Gases in Non-Critically Ill Neonates (PubMed)

Correlation and Interchangeability of Venous and Capillary Blood Gases in Non-Critically Ill Neonates Venous blood gas (VBG) is frequently used in the neonatal unit as alternative for capillary blood gas (CBG). However, studies reporting correlation are conflicting and data on interchangeability in neonates are lacking.We investigated the correlation and interchangeability of the components between VBG and CBG in infants admitted to the neonatal intensive care unit.In a prospective study (...) in the neonatal unit in Leiden University Medical Center (Netherlands), simultaneously VBG and CBG were withdrawn in neonates when both venous puncture and intravenous access as blood gas monitoring was indicated. From each blood gas analysis, a Pearson correlation, intraclass correlation, and Bland-Altman analysis was performed. Clinically acceptable difference for each blood gas value was defined up-front by means of an absolute difference: pH ± 0.05; partial pressure of carbon dioxide (pCO2) (±0.67 kPa = 5

18. The rate of blood loss from skin punctures during the Ivy bleeding time test (PubMed)

The rate of blood loss from skin punctures during the Ivy bleeding time test The rate of blood loss from skin punctures during the performance of the Ivy bleeding time test has been measured by a simple technique in normal individuals, in patients without defects of the haemostatic or coagulation system, and in patients with known haemorrhagic disorders.A wide range was found in normal individuals, but repeated tests on a single individual showed a smaller variation. Nearly half of the tests (...) on patients with von Willebrand's disease, thrombocytopenia, ;capillary type' of bleeding, or haemorrhagic renal failure gave abnormally high rates of blood loss. Haemophilic, Christmas disease, and Dinedevan-treated patients gave low volumes and rates of blood loss.A group of patients has been encountered in whom the bleeding time was normal but the rate of blood loss was increased. The majority of these had haemorrhagic symptoms and other evidence of a defective haemostatic or coagulation system

20. INVESTIGATIONS ON THE OXYGEN CONTENT OF CUTANEOUS BLOOD (SO CALLED CAPILLARY BLOOD) (PubMed)

INVESTIGATIONS ON THE OXYGEN CONTENT OF CUTANEOUS BLOOD (SO CALLED CAPILLARY BLOOD) 1. A procedure is devised whereby cutaneous blood (so called capillary blood) from a finger-tip can be obtained for gas analyses without coming in contact with the air. 2. Determination was made of the oxygen content of the arterial, cutaneous, and venous blood respectively from a normal resting individual, the arterial and cutaneous blood showing the same oxygen content (97.5 and 96.6 per cent of the total (...) oxygen-combining power of the blood). Venous blood drawn simultaneously was 75 per cent saturated. 3. Using the fact that there is a maximum value for the oxygen-combining power of the blood, we have shown, without doing arterial puncture, that under different conditions (normal and pathological individuals, resting and after exercise) the cutaneous blood and the arterial blood are almost identical as far as the oxygen content is concerned. 4. We think that we are justified in extending the identity
