This test returns a normal serum sodium level value between 135 and 145 mEq/L. Sodium blood test results typically take about two hours to come back.

Your doctor will then determine if you have a low or high sodium level in your blood. The results will be sent to your doctor when the sodium test is completed. If the level is above normal, it may indicate that you have a kidney problem or are taking too much salt (sodium). Perform an electrocardiogram (ECG) to check for abnormalities.Ī sodium blood test result will show how much Sodium is in your bloodstream.Calculate the sodium level according to known conversion factors.Determine sodium concentration using an automated analyzer.You will need to measure the salt in each sample using an appropriate measurement device. Measure total potassium and magnesium levels using specific assays.Collect your urine by placing a cup over your penis and letting it flow into the cup.Collect a blood or serum sample, insert a needle into one arm, and draw the blood into a tube.To perform a sodium blood test, these are the following procedures: You will also need to drink plenty of water so the lab can measure the amount of sodium in your blood or urine sample. To perform a sodium test, you must fast for at least eight hours before taking the sample. A level over 230 mg/dL is considered an emergency and indicates that you may have a serious kidney issue. Higher levels may be present if there is a problem with your kidney function.Screening levels are usually just over 140 mg/dL, below the normal range of 130-145 mg/dL.Your sodium level may be normal, low, or high, depending on your health condition. The normal range for whole blood sodium is 130-145 mmol/L, while the normal range for serum sodium is 136-153 mmol/L. A sodium test can measure the sodium level in either whole blood or serum. The sodium level in the body depends on the amount of water lost through sweat, urine, and faeces. Identify possible risk factors for developing consequences from chronic sodium deficits.Finding the root causes of undiagnosed hypertension and cardiovascular disease.For evaluation of the patient’s response to therapy for low sodium levels.To track the severity of a sodium shortage.For the following purposes, a sodium blood test is necessary: Sodium levels may be tested for, and the findings may be used to diagnose and treat various forms of hypertension. Pregnant or breastfeeding adults should consume no more than 1,000 mg daily (about ¼ tsp). Children under 18 should limit their intake to 1,500 mg daily (about ½ tsp). The National Institutes of Health recommends that adults consume no more than 2,300 mg daily (about 1 tsp). Sodium levels vary depending on a person’s age, sex, diet and activity level. Total tests combine direct and indirect measurements to calculate sodium concentration in the sample. Indirect tests use a chemical reaction to produce a signal representing the sample’s amount of sodium. There are three main types of sodium tests:ĭirect tests measure the amount of sodium present in a sample directly. A sodium blood test can help diagnose and monitor these conditions. Sodium levels in the bloodstream are affected by many factors, including diet, exercise, medical conditions, and medications. A sodium test typically involves collecting blood or other body fluid samples for testing. The test is used to diagnose and monitor certain diseases and conditions, such as high blood pressure and heart disease. A sodium test is a medical test used to determine the sodium level in a person’s blood or other body fluid.
