What are the meanings of the 19 indicators in blood routine?
The blood routine test report includes red blood cells (RBC), hemoglobin (HB), white blood cells (WBC), white blood cell count, hematocrit (HCT), and platelet count (PL). The normal reference values are indicated on the right side of the test report. The results obtained, in addition to numbers, also have symbols "↑" and "↓" indicating that they are higher or lower than the normal reference values.
What should be noted after a blood routine test?
(1) After drawing blood, local pressure should be applied at the needle hole for 3-5 minutes to stop bleeding. Caution: Do not rub to avoid subcutaneous hematoma.
(2) The pressing time should be sufficient. Everyone's clotting time varies, and some people require a slightly longer time to clot. So when the surface of the skin appears to have no bleeding and immediately stops compressing, it may cause blood to seep into the subcutaneous tissue and cause bruising due to incomplete hemostasis. Therefore, pressing for a longer time is necessary to completely stop the bleeding. If there is a tendency for bleeding, the compression time should be extended.
(3) After drawing blood, if symptoms such as dizziness, blurred vision, and fatigue occur, one should immediately lie down and drink a small amount of sugar water. After the symptoms subside, a physical examination can be conducted.
(4) If there is local congestion, apply a warm towel wet after 24 hours to promote absorption.
Through blood routine examination, problems in the patient's body can be detected in a timely manner, especially for some patients with blood diseases who need to undergo blood routine examination every day. The above is an introduction to the significance of the 19 indicators in blood routine. Patients must actively cooperate with doctors for blood tests after falling ill.
