What does the Kidney Function Test Detect?
They are two small secondary organs that produce urine. These are responsible for filtering toxins and achieving a balance of water, ions and pH.
Why get a Kidney Blood Test?
Additionally, pain can be caused by various causes and sometimes can be confused with back pain. When the kidneys are affected for various reasons, they can no longer balance salts, minerals, calcium and water.
However, please note that there are several risk groups for pain and disease:
- If you have diabetes.
- High Pressure.
- Family history of the disease.
- If you use prohibited substances.
Instructions for use:
Please take your sample in the morning. We advise that you use this for at least one hour before any medication.
5 BioMarkers
- Urea: gauges how well it is functioning.
- Creatinine: determines malfunction or failure.
- Phosphate: Is essential for producing energy, muscles, nerve function and bone growth. Measures the amount of phosphate.
- Albumin: measures the amount of protein in the transparent liquid portion.
- Bicarbonate: healthy organs help keep your bicarbonate levels in balance. Measures the amount of bicarbonate.

What are the Common Kidney Function Questions?
-
Q: Why are these organs so important?
- A: Because they filter and remove waste products, remove extra water from the body, produce hormones that help control your body and adjust levels of minerals and chemicals.
-
Q: But what can I do to protect them?
- A: Maintain a healthy diet and lifestyle, control your sugar, monitor your blood pressure, drink plenty of fluids, quit smoking, be aware of the number of over-the-counter pills you take, and have your sample at least once yearly.
-
Q: But what checks are done to assess it?
- A: Sampling: Urea, Creatinine, Phosphate, Albumin, Bicarbonate.
-
Q: What is related?
- A: Diabetes is the most common cause of chronic kidney disease. High sugar levels can damage the vessels and affect the organ’s filtering ability.
-
Q: How is High-Pressure Control related?
- A: High pressure damages the vessels and reduces the organ’s supply.
-
Q: And how can diet affect you?
- A: A healthy diet and lifestyle can reduce their workload and prevent or delay the further progression of your disease.
-
Q: What does the sample measure?
- A: To determine current Kidney health, the check measures the levels of numerous chemicals, including minerals, electrolytes, proteins, and sugar.
What is the Scientific Data from the Kidney Blood Test Instrument and Reagent Supplier?
Technology Method:
Fully automatic biochemistry analyser
Limit of Detection:
- Urea: 0.9 mmol/L
- Creatinine: 22 umol/L
- Phosphate: 1 mmol/L
- Bicarbonate: 0.749 mmol/L
- Albumin: 10 g/L
Accuracy and Precision:
- Urea: The approximate error is < ± 10%. The within-assay CV is ≤ 5%. The between-assay CV is ≤ 5%.
- Creatinine: The approximate error is < ± 15%. The within-assay CV is ≤ 3.62%. The between-assay CV is ≤ 4.12%.
- Phosphate: The approximate error is < ± 10%. The within-assay CV is ≤ 5%. The between-assay CV is ≤ 10%.
- Bicarbonate: The within-assay CV is ≤ 3.93%. The total precision is ≤ 7.86%.
- Albumin: The approximate error is < ± 4%. The within-assay CV is ≤ 3%. The between-assay CV is ≤ 5%.
Measuring Ranges:
- Urea: 0.9~35.7 mmol/L
- Creatinine: 22~3000 umol/L
- Phosphate: 0~4.0 mmol/L
- Bicarbonate: 0.749~47.1 mmol/L
- Albumin: 10~60 g/L
Validation-Active Information:
- EQA: NA
- Inter-laboratory validations
- Periodic according to the validation schedule
- Event-triggered- QC/Calibration/New materials/Batch
Accuracy and Precision:
The accuracy relies on the approximate error percentage. This percentage is the percentage deviation from the actual result. The precision relies on the within-assay coefficient of variations and the between-assay coefficient. The within-assay coefficient of variations is the variance of the result value if the same sample was analysed again. The between assay coefficient is the variance of the result value if the same sample was reprocessed from the beginning again.
In range results:
Urea: 2.9~8.2 mmol/L
Creatinine:
- Females: 35~80 umol/L
- Males: 44~97 umol/L
Phosphate: 0.81~1.45 mmol/L
Bicarbonate:
- Arterial: 21~28 mmol/L
- Venous: 22~29 mmol/L
Albumin: 34~48 g/L

Organ And Kindey Performance. Are yours working well?
A Kidney test is enough to investigate the health.
Many medical labs utilize blood tests to assess kidney function. For more insight, we spoke with Dr. Linda Fezzardi, director at the Chelsea Clinical Institute Analysis Laboratory.
Should we do the renal panel?
The renal panel includes a battery of tests useful for evaluating renal activity. These tests measure the quantity of various substances, including sugars, proteins, mineral salts and electrolytes.
Specifically, the exam included in the renal panel includes the measurement of:
- Glucose (which represents the main energy source of our body); proteins such as albumin (whose role in keeping fluids within the blood vessels and in the transport of hormones and vitamins is fundamental);
- Minerals such as phosphorus and calcium (the former essential for energy production, the latter essential for correct muscle, nervous system and heart activity);
- Electrolytes (important for maintaining acid-base balance but also for various body processes); waste products such as urea (released by the liver into the bloodstream and into the organ where it is filtered and eliminated through urine); and creatinine (waste product produced by muscles).
- Glomerular filtration rate: A value you should not underestimate
Another Kidney screening value to investigate that can be included within the renal function panel is the glomerular filtration rate (eGFR), thanks to which you can estimate the amount of blood filtered by the glomeruli in the organ in a minute.
The glomerular filtration rate is a formula that also takes into account some characteristics of the patient who performs it, such as:
- Age
- Type
- Race
- Weight
- Height
Various diseases can cause renal failure:
- Urinary tract infections;
- Calculations;
- Malformations;
- Hereditary diseases;
- Glomerulonephritis (diseases of inflammatory origin which particularly affect the glomeruli, causing generalized swelling and issues in the urine);
- High pressure (more rarely);
- Diabetes (more rarely).
- In renal failure, the organ’s “cleaning and “process” work is damaged. Older people are generally more likely to develop it.
Renal failure damages the kidneys’ “cleaning” and “process” work. Older people are generally more likely to develop it.
The rules
In addition to monitoring the activity over time, to balance the
onset of chronic diseases, it is suggested to adopt a healthy lifestyle by avoiding habits and behaviours such as:
- Sedentary lifestyle;
- Unregulated eating;
- Abuse of salt and tobacco;
- Prolonged drug intake.
- The extent of renal failure
Calculate the glomerular filtration rate to check the extent of renal failure. This allows one to estimate the leftover renal issues and follow their progress over time.
Based on the data, we divide further renal failure into different stages of severity:
In the early stages, you don’t feel any characteristic symptoms.
Only the blood values that specifically express renal function, i.e., creatinine, are altered. Subsequently, uric acid, calcium, phosphorus, bicarbonate, and parathyroid hormone levels are altered, and red cells are reduced.
Finally, in the
advanced stage, the symptoms of anaemia increase, pressure values rise, and it is necessary to take various drugs to correct the changes of all the issues so they can no longer function well.
If the situation worsens, i.e. when the glomerular filtration rate drops below 10 ml/min, cleaning with machines is likely.
