GetTested's Kidney test is a simple home test that you don't need to send to a lab for analysis; instead, you get immediate results. The kidney test measures creatinine, protein, and urine density via urine, and the test result is shown by visually comparing it with a color chart found inside the packaging.
About the Kidneys
The kidneys filter waste products and excess water from your blood, producing urine as a result. The small units inside your kidneys, called nephrons, are the actual filtering units. Each kidney has about a million nephrons. Most kidney diseases attack the nephrons and alter their ability to filter blood and produce urine.
Common Symptoms of Impaired Kidney Function
In the early stages of kidney disease, you usually don't feel sick at all. If it worsens, you may experience some of the following symptoms:

Feeling tired
Drowsiness or trouble concentrating
Loss of appetite / experiencing nausea and vomiting
Swelling or stiffness in the hands or feet
Frequent or less frequent urination
Muscle cramps (painful and involuntary muscle contractions)
Darkening of the skin

Storage
Store at room temperature 15-30°C. Do not store test strips in the refrigerator or freezer. Do not expose the test strips to moisture, heat, or light before use. Use the test strip immediately after opening the foil pouch.
How to Perform the Kidney Test
Start by collecting urine in a glass or cup. Take one test strip out of the packaging and hold the end that is completely white without colored squares. Dip the colored part of the test strip into the glass with urine for a maximum of one second. Remove the test strip and gently tap it against the edge of the glass to remove excess urine. Hold the test strip horizontally for 30-60 seconds to allow the reaction to occur. Read your result by comparing the color reactions on the strip with the color chart in the packaging.
Test Limitations
Substances that cause abnormal urine color, such as certain medications, can affect the color development on the test strip. The color development in the reaction area can be masked, or a color reaction may occur in the area that can be visually interpreted as a false positive. Therefore, it is recommended, in doubt, to repeat the test after finishing the medication (after consulting your doctor).
Protein: The minimum sensitivity of this test is 10-20 mg/dL of protein in urine. Highly buffered alkaline urines (pH 9) can give a false negative result. The interpretation of results is also difficult in cloudy urine samples.
Specific Gravity: Elevated specific gravity readings can be obtained in the presence of moderate amounts (100-700 mg/dL) of protein; specific gravity increases with the amount of glucose in the urine.
Creatinine: Low creatinine concentration may be associated with dilution.

Trimethylamine N-oxide (TMAO)

Trimethylamine (TMA) is a volatile organic compound produced in the gut through bacterial fermentation of dietary nutrients such as choline, L-carnitine, and lecithin. Typically, TMA is rapidly converted in the liver to trimethylamine N-oxide (TMAO), which is less toxic. However, elevated TMA levels can indicate imbalances in the gut microbiome or impaired liver detoxification capacity. High TMA is also linked to trimethylaminuria, a rare metabolic disorder that causes a strong body odour. Monitoring TMA provides insight into gut microbial activity, protein metabolism, and liver function.

Homocysteine is a sulphur-containing amino acid produced during the metabolism of methionine, an essential amino acid. It plays a key role in methylation, detoxification, and cardiovascular function. Elevated homocysteine levels have been associated with increased risk of heart disease, stroke, cognitive decline, and pregnancy complications. Imbalances may be caused by deficiencies in B vitamins (especially B6, B12, and folate), impaired methylation, or genetic variants like MTHFR. Monitoring homocysteine levels can provide valuable insights into cardiovascular, neurological, and metabolic health.

Alpha-ketoglutarate (AKG) is a key compound in the Krebs cycle, an essential metabolic pathway for energy production in cells. It plays a crucial role in converting nutrients into energy, amino acid metabolism, and nitrogen transport. Additionally, Alpha-ketoglutarate is involved in various cellular processes, including signaling and regulation....

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.

Absolutely perfect, results came after few days and finally after a lots of times visited GP, we finally know why my son has eczema - he is allergy to carrot. Thanks a lot.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
