Question:

What to do if a measurement with Starrsed Control is not exactly the expected value

Hint:

A measurement with Starrsed Control is not a calibration of the Starrsed instrument, but a control tool to measure the stability of the instrument over a longer period.

Therefore a default standard range is given. It is possible to use a narrower or wider value range, the default value range (+/-5 for Normal and +/- 10 for Abnormal) is generally sufficient.

Additional information

Using a different value range can depend on the general average of measured QC ESR's, but also on the Standard Deviation, the Coefficient of Variation and general trends of QC measurements in a longer period.

Applicable for:

Interrliner
Starrsed RS
Starrsed ST
Starrsed TL
Starrsed Compact
