NCT02711332 | Completed

• 1 other identifier: K@Home_1
• Study Type: observational
• Target: 22
• Locations: 0 countries
• Sites: N/A

Brief Summary

This is an open, single-centre trial investigating the impact of haemolysis after capillary blood collection to the measured potassium concentration in Plasma healthy subjects. Each subject will have four capillary blood collections on different fingers. Two on the right and two on the left hand. Additionally as a reference a venous blood collection will be conducted.

Conditions

Hemolysis

Outcome Measures

Primary Outcomes (1)

• Measured potassium concentration in capillary blood tests compared to venous blood tests.

  1 hour

Secondary Outcomes (2)

• Correlation from fHb and potassium

  1 hour

• Degree of haemolysis in capillary blood tests compared to venous blood tests.

  1 hour
