What does high Sodium and RDW mean in blood test?

High Sodium and RDW can be caused by numerous problems.

But if Sodium and RDW levels exceed these levels, you should see a doctor immediately.

How is a blood test performed in the lab?

Depending on the symptoms you are experiencing, your doctor may order a Sodium and RDW test. In most hospitals Sodium and RDW results can be obtained within three to six hours after blood is taken. The blood is usually drawn from a vein on the inside of the elbow or the back of the hand. Drink plenty of water before your appointment. If you experience any symptoms that you are concerned about are out of the ordinary, call your doctor immediately.
