What's

Reticulocyte %

Reticulocyte percentage is a way to measure the amount of new red blood cells your body is making, which can show how well your bone marrow is working. Reticulocytes are young red blood cells that are released into your bloodstream before they are fully grown. Their job is to carry oxygen from your lungs to the rest of your body, which is important for keeping your energy levels up and maintaining good health. The reticulocyte percentage provides a quick look at how well your body is replacing its red blood cells, something that is always happening as older cells naturally break down.

If Your Levels Are High

A high reticulocyte percentage means your body is making more red blood cells than usual. This can happen for various reasons, such as your body trying to make up for a lack of healthy red blood cells in cases like anemia or after losing blood. It can also be a response to being in high-altitude areas where there's less oxygen, so your body needs more red blood cells to carry the oxygen it requires. Additionally, certain medications or treatments, like chemotherapy or drugs for kidney disease, might cause your body to produce more red blood cells.

Symptoms of High Levels

Symptoms of high levels of Reticulocyte % might not be directly noticeable, as they often relate to the underlying condition causing the increased production. However, some people may experience fatigue, shortness of breath, or a rapid heart rate, which are common signs of conditions like anemia or blood loss.

If Your Levels are Low

A low reticulocyte percentage means your body might not be making enough new red blood cells. This can happen for various reasons, such as not having enough iron, vitamin B12, or folate in your diet, which are all important for creating red blood cells. Some medications or chronic illnesses could also affect your bone marrow's ability to make these cells, as well as certain genetic conditions. Another possibility is that your body is using up red blood cells faster than it can make them, which can occur in conditions like hemolytic anemia.

Symptoms of Low Levels

Symptoms of low levels of Reticulocyte % could include fatigue, weakness, pale skin, shortness of breath, and dizziness.
