Why Blood Glucose Matters Maintaining healthy blood sugar levels is critical. Chronic elevation leads to type 2 diabetes , a major risk factor for cardiovascular disease, kidney failure, nerve damage, and blindness. Monitoring can help manage or prevent diabetes through lifestyle changes and medication. 5. Hemoglobin and Hematocrit These tests assess the oxygen-carrying capacity of the blood. Hemoglobin is a protein in red blood cells that carries oxygen. Hematocrit is the percentage of blood volume made up by red blood cells. Normal Ranges Hemoglobin : Men: 13.8–17.2 g/dL Women: 12.1–15.1 g/dL Hematocrit : Men: 40.7–50.3% Women: 36.1–44.3% Importance Low levels may indicate anemia , leading to fatigue, Blood Vitals Reviews , and shortness of breath. High levels could suggest dehydration or other underlying conditions. 6. Blood Oxygen Saturation (SpO₂) Measured using a pulse oximeter , SpO₂ indicates the percentage of oxygen in the blood. Normal Range : 95–100% Below 90% : Hypoxemia (requires medical attention) Significance SpO₂ is crucial in monitoring respiratory health, especially in conditions like COPD , COVID-19 , or asthma . Sudden drops may indicate worsening of respiratory function. 7. Cholesterol and Lipid Profiles The lipid profile measures: Total Cholesterol Low-Density Lipoprotein (LDL) – “Bad” cholesterol High-Density Lipoprotein (HDL) – “Good” cholesterol Triglycerides Optimal Ranges Total Cholesterol : < 200 mg/dL LDL : < 100 mg/dL HDL : > 60 mg/dL Triglycerides : < 150 mg/dL Official Website https://blood-vitals.co.uk/
