Blood Urea Nitrogen (BUN) What other tests are used with the blood urea nitrogen test to check how my kidneys are functioning? BUN and creatinine are the primary tests used to check how well the kidneys are able to filter waste products from your blood. Your healthcare provider may also order a renal panel or electrolyte tests, such as sodium and potassium, or calcium to help understand how your kidneys are functioning. ^ Back to top.

Blood Sodium Test The sodium blood test is often part of a basic metabolic panel. This is a group of related tests. The basic metabolic panel includes tests for: calcium; bicarbonate; chloride; creatinine; glucose; potassium; sodium; blood urea nitrogen; Blood sodium can also be part of an electrolyte panel. Electrolytes are substances that carry an electrical charge. Potassium and chloride are other electrolytes. This test may be ordered if you have: eaten large amounts of salt ; not eaten enough or had enough water; a serious illness, or gone through surgery; received intravenous fluids

Chem 7 Blood Test Components slide 1 of 6. Chem 7 Components The chem 7 blood test checks the levels of creatinine, blood urea nitrogen (BUN), carbon dioxide, chloride, glucose, sodium and potassium in the blood. This allows doctors to identify diseases and disorders of the kidneys and screen for diabetes and other blood sugar disorders.

- Since magnesium is an electrolyte, a magnesium test may be ordered along with other electrolytes such as sodium, potassium, chloride, bicarbonate (or total CO2), calcium, and phosphorus to evaluate a person's electrolyte balance. If magnesium is low, it is not unusual for potassium also to be low.

What are the symptoms of hyponatremia (low blood sodium)? The chemical notation for sodium is Na. When combined with chloride (Cl), the resulting substance is table salt (NaCl). The normal blood sodium level is 135 - 145 milliEquivalents/liter (mEq/L), or in international units, 135 - 145 millimoles/liter (mmol/L).

Chloride (Cl)  [en EspaÃ±ol] Tests for sodium, potassium, and bicarbonate are usually done at the same time as a blood test for chloride. Most of the chloride in your body comes from the salt (sodium chloride) you eat. Chloride is absorbed by your intestines when you digest food. Extra chloride leaves your body in your urine.

- The diagnosis is based on blood tests indicating that the sodium level is high. Doctors may do further testing to identify the cause of the hypernatremia, including measurements of urine volume and concentration.

Medical Dictionary A sodium test checks how much sodium (an electrolyte and a mineral) is in the blood. The normal values listed here-called a reference range-are just a guide. These ranges vary from lab to lab, and your lab may have a different range for what's normal. Your lab report should contain the range your lab uses.

hypernatremia The normal concentration of sodium in the blood plasma is 136-145 mM. Hypernatremia is defined as a serum sodium level over 145 mM. Severe hypernatremia, with serum sodium above 152 mM, can result in seizures and death. Sodium is an atom, or ion, that carries a single positive charge.

Serum Sodium Your blood sodium level represents a balance between the sodium and water in the food and drinks you consume and the amount in your urine. A small amount is lost through stool and sweat. Many things can affect this balance. Your doctor may order this test if you: 1  Have had a recent injury, surgery, or serious illness.
