• Learn operation of Erba XL-640 and Erbachem.
• Select equipment from the list below.
  • Use Erba XL-640 as peferred equipment.
  • If Erba XL-640 is malfunctioning and can not be repaired within period acceptable to clinicians, use Erbachem and follow procedure for responding to Erba XL-640 failure
• Read following documents

Special instructions for patients

Note: Following instruction is useful only if operator is familiar with Erbachem

1. Run all testing material as sample (as described below at Sample Examination)
2. Evaluate calibration and QC absorbances in spreadsheet. Compare with past results.
3. If results are acceptable, enter the factor in the erbachem and set decimal place to zero.

1. Check aspiration volume of 300 microliter in test parameter of Creatinine.
2. Run Randox Human assy control-2(QC 5),1 Randox Human assy control-3(QC 8) in each and every batch. See Assigned values of target values of QC here
3. Select “Run test” → CRE in Erbachem menu.
4. When instrument asks “Aspirate water”, aspirate water.
5. When instrument asks “Aspirate sample”.
6. Mix Creatinine reagent R1 and R2 in equal quantity.
7. Take 500 microliter of mix (R1+R2) reagent in ependroff cup
8. add 50 microliter sample to it
9. Take reading immediately at 505 nm.
10. Total time taken for analysis is 90 seconds. (delay time 30 seconds + reading time 60 seconds)
11. Evaluate QC results. If QC results show major deviation from past, rerun batch.
12. If result is more than 20.0mg/dl then dilute the sample with DI water and rerun the sample.
13. Enter Calibration in LIS
14. Enter QC results manually in LIS
15. Enter sample results manually in LIS
16. instructions for determining quantitative results when a result is not within the measurement interval: Dilution of sample with DI water is done in same way as done by Erba XL-640 automatically.

1. Currently serum and urine are accepted as sample type.
