What it measures
Complete Blood Count Test (CBC)
Clinical significance
A red cell distribution width (RDW) test is a measurement of the range in the volume and size of your red blood cells (erythrocytes). Red blood cells move oxygen from your lungs to every cell in your body. Your cells need oxygen to grow, reproduce, and stay healthy. The RDW-CV is a calculation based on both the width of the distribution curve and the mean cell size. It is calculated by dividing the standard deviation of the mean cell size by the MCV of the red cells and multiplying by 100 to convert to a percentage.
Normal reference range of RDW-CV in human red blood cells is 11.5–15.4%. If anemia is observed, RDW test results are often used together with mean corpuscular volume (MCV) results to determine the possible causes of the anemia.
A low RDW means your red blood cells are all about the same size. A high RDW means you have both very small and very large red blood cells.
Real ratings and reviews from the Healsens app on the App Store and Google Play.
That's when I turned to a nutritionist and ordered a blood test through Healsens. … Four months later, I retested. My biological age dropped to 24—nearly a decade younger than my real age.
Read on App Store →It helps me track main parameters, understanding what do they mean and correlations, and make critical analysis to make preventative changes. Hope too see new fichas soon!
Read on App Store →Everything is great! Excellent app! It's very convenient for storing all your test results! The only thing I wish was that you could record blood pressure readings for both arms, as this is sometimes important for blood pressure monitoring.
Read on Google Play →A useful app. It motivates me to lead a healthy lifestyle and monitor my diet. After the test results, I decided to change my diet – I cut out flour and chocolate. I lost 2 kg in about a week. We'll see how the test results look over time.
