RBC
The RBC test measures the number of red blood cells (RBCs) in your blood. Clinicians often order this test to assess your overall health, diagnose conditions such as anemia or polycythemia, and monitor medical treatments. It is typically used in clinical situations where symptoms like fatigue, weakness, or unusual bruising are present. The RBC test provides valuable information about your blood's ability to carry oxygen throughout your body, making it a crucial diagnostic tool for various health assessments.

Clinical Information
Clinical Significance
Abnormal results from the RBC test may indicate various conditions. A low RBC count could suggest anemia, which can be due to nutritional deficiencies, chronic diseases, or bone marrow problems. Conversely, a high RBC count might indicate dehydration or other conditions like polycythemia. It’s important to remember that only a healthcare provider can interpret the results accurately and provide appropriate context and guidance.
Reference Ranges
Reference ranges for the RBC test can vary based on factors such as age, sex, and laboratory methods. Generally, these ranges indicate what is considered normal for healthy individuals. Your healthcare provider will interpret your results in the context of these ranges and your overall health.
Sample Preparation
Before your RBC test, there are generally no special preparations required. You can eat and drink normally before the test, though it’s always a good idea to inform your healthcare provider about any medications you are taking. If there are any specific instructions, your doctor will let you know ahead of time. Being well-hydrated may help with blood sample collection.
