Skin Puncture Phlebotomy Procedures
Numerical Order | Procedure |
---|---|
1 Rationale | Point-of-care-testing diabetes mellitus |
2 Equipment | Safety automatic lancet |
3 Equipment | 3 alcohol/acetone or alcohol preps |
4 Equipment | HemoCue blood glucose monitor |
5 Preparation | Gather equipment: safety automatic lancet. |
6 Preparation | Identity the patient properly. Briefly explain the test to the patient. |
7 Preparation | Clean your hands. |
8 Preparation | Put on gloves. |
9 Preparation | Select the site and cleanse it with antiseptic (especially the side of a finger). |
10 Preparation | Cleanse the site with an alcohol wipe and allow the skin to dry. |
11 Preparation | Without touching the cleansed site, gently massage the finger a few times from base to tip to aid blood flow. |
12 Preparation | Decide on which side of the finger to make the incision. |
13 Preparation | Remove the safety lancet from the protective paper without touching the tip, and as you hold the patient's finger firmly with one hand, make a swift, deep puncture with the retractable safety puncture device. |
14 Preparation | Wipe the first 3 drops of blood away with clean gauze. |
15 Preparation | Gently massage the finger from base to tip to obtain the needed drop of blood. Do not squeeze the fingertip, because this can cause hemolysis of the blood sample. |
16 Preparation | Apply the HemoCue microcuvette to the drop of blood. The correct volume is drawn into the cuvette by capillary action (capillary, venous, or arterial blood can be used). |
17 Preparation | Wipe off any excess blood from the sides of the cuvette. |
18 Preparation | Place the microcuvette into the cuvette holder and insert it into the phomometer. |
19 Preparation | The laboratory test result is displayed automatically. |
20 After the Procedure | Discard the safety automatic lancet in the sharps container with biohazard label. |
21 After the Procedure | Discard the gauze, alcohol wipes, and gloves in biohazard waste containers. |
22 After the Procedure | Wash or sanitize your hands. |
