Why would my red blood cell count be high and low?

Anemia or polycythem. Many conditions that cause anemia can cause your red cells to go low including blood loss, blood destruction and overproduction. Excess red cells can result from chronic hypnotic states and various forms of polycythemias.
It can't . It can't be high and low at the same time but there are many conditions that can cause anemia (low red blood cell count) or polycythemia (high red blood cell count). What exactly do you wish to know?

Balance prod/loss & Internal controls. Red blood cells typically live about 3 months, are constantly rupturing, dying (any bleeding increases loss rates) & replaced by division + release of new red cells from the bone marrow. Kidneys play a significant role by producing the hormone erythropoietin which stimulates marrow production & release. Ultimately the system is under brain control but not all issues understood.

What is the reason for the low red blood cell count and the high proportion of reticulocytes?

Can't say & resupply. Low red cell count is either from lack of production, early destruction, or loss (= bleeding). That part of question depends on your Dr's eval and testing. Reticulocytes are young (/"immature") red blood cells. When RBCs are needed, production in bone marrow ramps up and cells are released a little early, which can tell on CBC. Read more...

Is there something that can cause my red blood cell count to fall as low as a 6?

Is this your Hemoglo. Red cell count runs into 4-5 million cell count range. If yours is 6...You probaly are talking about hemoglobin(hb) level. This is normally 12-14 grams. Anything less than 12 is called anemia. Anything below 10 grams will make you feel weak, and less than 8 grams requires a blood transfusion.

What does a high number of red blood cell count signify? My recent blood test came back and my red blood cell count is above the reference range. 7.64

Not very significant. Slight increase in RBC's may be a compensatory reaction to blood loss either external from injury or internal like a bleeding ulcer. Excessive increase in RBC count can be due to bone marrow disease. Repeat the count after a few months and if it is still high consult a hematologist. Read more...
