Urea
Urea is a waste product formed in the liver through the breakdown of proteins. After formation, it is transported to the kidneys and eventually excreted in the urine. Measuring urea levels in the blood, often called blood urea nitrogen (BUN), is a common test used to evaluate kidney function. Elevated blood urea levels can indicate impaired kidney function or other issues affecting waste processing and excretion.
Description
Individuals who would benefit from testing their urea levels include those with conditions that can affect kidney function, such as diabetes, high blood pressure, heart disease, and chronic kidney disease. It’s also important for people who show symptoms of kidney dysfunction, such as reduced urine output, swelling in the legs or abdomen, fatigue, and confusion. Regular monitoring of urea levels is also crucial for those undergoing treatments that can affect kidney function, such as certain medications or chemotherapy.
Symptoms of High Urea Levels:
-
- Fatigue and weakness.
- Decreased appetite or weight loss.
- Swelling in the face, hands, feet, or abdomen.
- Shortness of breath.
- Changes in urination patterns.
- Dry or itchy skin.
- Confusion or difficulty concentrating.
Symptoms of Low Urea Levels:
-
- Low urea levels are less common and usually not a concern unless they indicate severe liver damage or malnutrition.
- Symptoms might include issues related to the underlying liver condition or poor nutritional status.
Improving urea levels typically involves addressing the underlying cause of the abnormal levels. For high urea levels, this could include managing conditions that impair kidney function, such as controlling diabetes or hypertension, adjusting medication dosages, or treating dehydration. Dietary changes, especially reducing protein intake, can also help in managing urea levels. For low urea levels, treatment focuses on the underlying causes, such as improving liver function or addressing nutritional deficiencies.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.
