Abnormal hCG levels can be indicative of several conditions. Low levels of hCG may suggest a potential miscarriage, ectopic pregnancy, or issues with the pregnancy's viability. High levels of hCG can indicate multiple pregnancies (e.g., twins or triplets), molar pregnancy, or certain types of cancers such as choriocarcinoma. Nurses must be vigilant in recognizing these patterns and collaborating with healthcare providers for appropriate follow-up and intervention.
