In general, around 7 to 20 mg/dL (2.5 to 7.1 mmol/L) is considered normal. But normal ranges may vary, depending on the reference range used by the lab, and your age. Ask your doctor to explain your results. Urea nitrogen levels tend to increase with age.

What are normal blood creatinine levels? Normal levels of creatinine in the blood are approximately 0.6 to 1.2 milligrams (mg) per deciliter (dL) in adult males and 0.5 to 1.1 milligrams per deciliter in adult females.

According to the Mayo Clinic, a normal range of potassium is between 3.6 and 5.2 millimoles per liter (mmol/L) of blood. A potassium level higher than 5.5 mmol/L is critically high, and a potassium level over 6 mmol/L can be life-threatening. Small variations in ranges may be possible depending on the laboratory.

A normal healthy person will have an HbA1c level under 42 mmol/mol. Pre-diabetes ranges from 43-47 mmol/mol. Above that is diabetic level.

So the liver converts the ammonia to a non-toxic compound, urea, which can then be safely transported in the blood to the kidneys, where it is eliminated in urine. An adult typically excretes about 25 grams of urea per day.

The normal range for neutrophils is usually between 2 billion and 7.5 billion neutrophils per litre of blood. To make these large numbers easier to manage, they are written down as 2.0 x 109/L to 7.5 x 109/L.

Normal values of total bilirubin are from 0.3–1.0 mg/dL. The indirect bilirubin level in the bloodstream is the total bilirubin minus the direct bilirubin levels in the bloodstream. Additionally, normal reference ranges may vary from lab to lab. In a newborn, higher bilirubin is normal due to the stress of birth.

Ranges. The National Institutes of Health cite normal blood pressure to be below 120 mm Hg systolic and 80 mm Hg diastolic.

If your blood sample is being tested only for blood urea nitrogen, you can eat and drink normally before the test. If your blood sample will be used for additional tests, you may need to fast for a certain amount of time before the test. Your doctor will give you specific instructions.

In patients undergoing dialysis; a normal blood pressure may be defined as the mean ambulatory blood pressure less than 135/85 mmHg during the day and less than 120/80 mmHg by night.

A normal level of NT-proBNP, based on Cleveland Clinic's Reference Range is: Less than 125 pg/mL for patients aged 0-74 years. Less than 450 pg/mL for patients aged 75-99 years.

Azotemia and uremia are two different types of kidney conditions. Azotemia is when there's nitrogen in your blood. Uremia occurs when there's urea in your blood. However, they're both related to kidney disease or injury.

The ammonia blood test is the gold standard for diagnosing urea cycle disorders. Too much ammonia in your body can cause psychological problems like confusion, tiredness, and possibly coma or death. A child's reaction to too much ammonia can include seizures, breathing trouble, lower response, and potentially death.

Recommended HDL range Typically, doctors recommend an HDL level of 60 milligrams per deciliter (mg/dL) of blood or higher. HDL that falls within the range of 40 to 59 mg/dL is normal, but could be higher. Having HDL under 40 mg/dL increases your risk of developing heart disease.

Nitrogen metabolism is necessary for normal health. Nitrogen is an essential element present in all amino acids; it is derived from dietary protein intake, is necessary for protein synthesis and maintenance of muscle mass, and is excreted by the kidneys.
