Proteinuria screening test (Protein Creatinine Ratio Urine Test) as an aid in early detection of PREECLAMPSIA, 50’s
- Urine based
- Qualitative and semi-quantitative results in 60 seconds
- Measures the protein:creatinine ratio
- Visual reading and analyzer ready
- Cost equivalent to protein-only dipsticks
- Complements clinical findings and patient history
- Sensitivity and specifity of 85% and 84% [95% Cl]
The PrCr Test Strips is used as a preliminary screening test for proteinuria and the risk of pre-eclampsia/eclampsia. The test result is the ratio of Protein to Creatinine in the urine. A ratio of 0.30 or higher indicates significant proteinuria and therefore a high risk for pre-eclampsia/eclampsia.
Instructions for Use
Check the color label that the expiry date and maximum storage temperature of the test strips have not been exceeded. Do not use if product is beyond the expiry date, or if stored at wrong temperatures.
Ask the patient to collect midstream urine in a clean container, free of any disinfectant or soap residue. The urine sample is handed to a healthcare worker for testing.
Now, remove one test strip from the container. Do not touch the reagent areas. Immediately close the container securely using the original cap. Briefly (1 second only), dip the test strip into the urine so that both reagent pads are wet, then remove.
Blot the side of the test strip on absorbent paper to remove excess urine.
Start the clock.
After exactly 60 seconds, compare the colors on the test strip with the color scale on the container and immediately write down the results.
How to Estimate Proteinuria
In the table to the left, find the PROTEIN 2+ value on the top row, and then find the CREATININE 3+ value on the left row as indicated. Find the spot on the table where the PROTEIN 2+ and the CREATININE 3+ meet. In example 1 above, the 2 values meet on a RED colo r block, which suggests Proteinuria.
In the table to the left, find the PROTEIN 1+ value on the top row, and then find the CREATININE 4+ value on the left row as indicated. Find the spot on the table where the PROTEIN 1+ and the CREATININE 4+ meet. In example 2 above, the 2 values meet on a GREEN color block, which suggests Proteinuria is NOT present (Normal).
