Embodiment

[0030] Example 1: Using 70% isopropanol and 2% K 2 A method of minimizing coagulation in a blood sample obtained from an adult human finger with a liquid composition of EDTA.

[0031] Prepare 2% K using conventional methods 2 EDTA liquid composition. The patient is seated in a chair and asked to stretch the nondominant hand as far as possible. Select the middle finger as the skin surface location to be incised. Patients are instructed to wash their hands with soap and warm water. While still cold to the touch, wrap the patient's hand in a warm, moist towel (not higher than 40°C / 105°F) for two minutes while keeping her hand in a downward position to increase gravity towards the hand Department of blood supply. The technician performing the collection wears latex gloves. The patient's finger is wiped clean with a cotton swab soaked in a 70% isopropanol solution. Air dry your fingers. Then 2% K 2 EDTA anticoagulant blood solution was wiped on the pad of the middle finger...

Embodiment 2

[0032] Example 2: Using 70% isopropanol and 2% K 2 A method of minimizing coagulation in a blood sample obtained from an infant's heel with a liquid composition of EDTA.

[0033] Blood collection sites were selected from an area encompassing at least 1 cm on either side of an imaginary line placed on the sole of the infant's foot and along its length. Wash the area thoroughly with soap and warm water and dry with a clean towel. 2% K with a cotton swab 2 A liquid composition of EDTA and 70% isopropanol was applied to the sampling site. Use a 0.25 gauge (0.51 mm O.D.) lancet to puncture the skin to a depth of approximately 1.0 mm. Allow blood to pool at the puncture site. Blood is collected using a capillary connected to a container. Apply 1% w / v CaCl to the puncture site 2 70% isopropanol solution to wipe.

Abstract

The invention sets forth a method for reducing coagulation in a blood sample collected most conveniently from an acral body site such as the fingertip or heel, commonly referred to as capillary blood collection. The method includes the steps of applying an anticoagulant composition to the acral site, lancing the skin in contact with the anticoagulant composition and allowing blood and anticoagulant to mix on the skin at the site prior to collecting the blood for analysis.

Description

Background of the invention [0001] The present invention involves taking a blood sample using a technically simple procedure such as incision of the skin at a superficial or "extremity" body location. This sampling method is suitable for collecting samples by relatively untrained individuals in a non-clinical setting. The ability to obtain blood samples in this manner facilitates economical and readily available point-of-care clinical laboratory point-of-care testing. The present invention can be used in conjunction with current state-of-the-art miniaturized blood analysis instruments intended for use in private homes, rural areas, or other isolated settings where more invasive and dangerous methods and larger analytical instruments are not possible or likely to be used . [0002] Advances in the miniaturization of medical devices have made possible more precise blood analysis using much smaller blood volumes than traditionally required. These advances have made it possible...
