What does high Sodium and RDW SD mean in blood test?

High Sodium and RDW SD can be caused by numerous problems.

High levels of Sodium and RDW SD in the blood indicate a variety of health problems. If your blood Sodium level is between 136 mmol/L to 145 mmol/L and the RDW SD level is between 39 mmol/L to 46 fL, then your body does not have any underlying health problems. But if Sodium and RDW SD levels exceed these levels, you should see a doctor immediately.
