What does it detect?

The kidneys are two small secondary organs that produce urine. These are responsible for filtering toxins from the blood and achieving a balance of water, ions and pH.

5 BioMarkers:

Urea: gauges how well they are functioning.
Creatinine: determines malfunction or failure, level of creatinine. Blood serum creatinine.
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 of the blood.
Bicarbonate: healthy organs help keep your bicarbonate levels in balance. Measures the amount of bicarbonate in your blood.

Please take the sample in the morning before eating or drinking.

What is the Scientific Data from 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: Yes
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 test 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
