Do you know the Kidney Function Blood Test Kit?
Kidney Function Kit. There are two of them in your body. They are small secondary organs and they mainly produce urine to be excreted. They filter out toxins from your body and maintain water, ion, and pH balance inside your body systems.
For what reason should I get a Kidney Blood Test?
You might experience pain caused by problems in this organ and confuse it for back pain. If this organ is not working correctly, the balance of various substances such as salts, minerals, and water cannot be regulated correctly.
Please note that these are the relevant risk groups for pain and disease:
- You are Diabetic.
- You have High Blood Pressure.
- Family history of the disease.
- You use prohibited substances.
Instructions for use:
It is best that you collect your Urea Creatinine samples in the morning and at least an hour before taking any medication you are currently on.
5 Biomarkers
- Urea: Gauges kidney function.
- Creatinine: Shows kidney failure.
- Phosphate: Energy production, muscle and bone health.
- Albumin: Protein in the transparent liquid portion of the blood.
- Bicarbonate: Its balance is maintained by your kidneys.
What are some Kidney Function Steps I can follow to Order?
Buy the Kidney kit online and collect your samples as instructed.
Drop your sample parcel off at the nearest Royal Mail Red Street Box, ideally before collection times. Use the Track 24/48 return label for lab deliveries.

What are the Kidney Frequently Asked Questions?
Q: What is the significance of these organs?
- A: Due to their ability to filter and eliminate waste products, remove excess water from the body, produce hormones that aid in body regulation, and regulate mineral and chemical levels.
Q: However, what measures can I take to safeguard them?
- A: It is important to maintain a healthy diet and lifestyle, control your sugar, monitor your blood pressure, consume plenty of fluids, quit smoking, be aware of the number of over-the-counter pills you take, and have your sample taken at least once a year.
Q: What types of evaluations are done?
- A: Urea, Creatinine, Phosphate, Albumin, and Bicarbonate.
Q: What is the connection?
- A: Chronic kidney disease is most frequently caused by diabetes. The organ’s filtering capacity can be impacted by high sugar levels, which can harm the vessels.
Q: What is the relationship between High-Pressure Control and other topics?
- A: The organ’s supply is reduced and the vessels are damaged by high pressure.
Q: Additionally, what is the impact of diet on your health?
- A: By adhering to a nutritious diet and lifestyle, they can mitigate their burden and impede or postpone the further progression of your illness.
Q: What are the sample’s measurements?
- A: The check assesses the levels of a variety of substances, such as minerals, electrolytes, proteins, and sugar, to ascertain the current state of kidney health.
Kidney Scientific Specifications from Our Equipment and Reagent Suppliers
Technology Method:
Fully automatic biochemistry analyser
Detection Restrictions:
- 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 Performance: Are your Kidneys working well?
A test for it is sufficient to evaluate one’s health.
Studies are employed by numerous medical laboratories for evaluation. We also conducted an interview with Dr. Linda Fezzardi, the director of the Chelsea Clinical Institute Analysis Laboratory, to gain further insight.
Should we do the renal panel?
The renal panel is useful for evaluating 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 screening value to investigate that can be included is the glomerular filtration rate (eGFR), thanks to which you can estimate the amount of blood filtered in a minute.
The 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 causes generalized swelling and issues in the urine);
- High pressure (more rarely);
- Diabetes (more rarely).
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 and 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 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 it drops below 10 ml/min, cleaning with machines needs to be done.
