Coagulation tests on capillary blood. A screening procedure for use in small children

Area of Science:

• Hematology
• Clinical Pathology
• Coagulation Science

Background:

• Investigating the blood coagulation mechanism is crucial for diagnosing and managing bleeding disorders.
• Existing methods for coagulation testing can be complex or time-consuming.
• The need for reliable and efficient pre-operative screening for clotting defects is paramount.

Purpose of the Study:

• To describe a novel method for investigating the coagulation mechanism.
• To compare the results of the new method with established coagulation tests.
• To evaluate the reliability of the new method as a pre-operative screening tool.

Main Methods:

• A new method for investigating blood coagulation was developed and described.
• Results from the new method using capillary blood were compared with standard tests on venous blood.
• Simultaneous testing was performed on normal subjects and patients with clotting defects.

Main Results:

• A good correlation was observed between the new method's results (P and P tests) on capillary blood and standard venous blood tests.
• Thromboplastin screening tests on capillary blood correlated well with antihaemophilic and Christmas factor levels.
• The described methods demonstrated reliability in routine use over a two-year period.

Conclusions:

• The newly developed method provides a reliable means of investigating the coagulation mechanism.
• The method is suitable for pre-operative screening of clotting defects.
• The findings support the use of this method in routine clinical practice for enhanced patient safety.
