The topic Molar pregnancy while discussing about the indications for GTN

Could u please clear my doubt!! why plateau of high serum hCG is not the correct answer as u told in the video of the topic Molar pregnancy while discussing about the indications for GTN

Ma’am has told the number of theca lutein cysts are not indicative the size is.

Yes I understood that but my doubt still remains same mam has also told the this plateau reading of hcg js indicator for invasive mole

I guess here in option time period for plateau hcg is not given exactly so this is not the indicator … Ma’am told that plateau hcg in 4 weeks …
