What is considered abnormal in a PCR reflecting PET?

The presence of protein in the urine is a key marker when assessing for preeclampsia and can be detected using a protein-to-creatinine ratio (PCR). In this context, a PCR value greater than 30 mg/mmol signifies that there is a concerning level of protein present and is considered abnormal. This level indicates a potential disruption in kidney function or other systemic issues that are common in preeclampsia.

The measurement reflects how much protein is being excreted relative to creatinine levels, which helps to provide a clearer picture as creatinine levels can fluctuate due to various factors. A PCR greater than 30 mg/mmol suggests a significant urinary protein excretion rate that warrants further investigation or monitoring.

The other values listed are either within normal limits or do not accurately represent the threshold considered abnormal for a PCR associated with preeclampsia. This makes the provided answer of greater than 30 mg/mmol the appropriate choice.
