Human chorionic gonadotropin (hCG) is a hormone produced by trophoblast tissue, which is typically found in early embryos and eventually develops into part of the placenta. Measuring hCG levels can help distinguish between normal and abnormal pregnancies and is also useful for monitoring after a pregnancy loss. In addition, hCG testing can aid in the diagnosis of certain cancers, such as choriocarcinoma and some extra-uterine malignancies. Exogenous administration of hCG as a bolus is standard practice for in vitro fertilization transfer care.

In pathological conditions such as gestational trophoblastic disease—including hydatidiform mole, choriocarcinoma, and germ cell tumors—hCG is produced in excess due to abnormal trophoblastic proliferation, resulting in markedly elevated serum levels. These abnormal elevations can aid in the diagnosis and monitoring of treatment response.

Effective patient-centered care involving hCG testing and interpretation requires a collaborative, multidisciplinary approach grounded in strong clinical skills, strategic planning, ethical integrity, and seamless communication. Clinicians and advanced practitioners must possess the diagnostic acumen to interpret hCG levels within the appropriate clinical context, whether to confirm pregnancy, monitor gestational complications, or identify malignancies. Nurses play a vital role in specimen collection, patient education, and emotional support, ensuring patients understand the purpose and implications of hCG testing. Pharmacists contribute by evaluating the potential effects of medications on hCG levels and supporting informed therapeutic decisions. Understanding the utility and variability of different hCG assays is clinically relevant to a wide range of medical professionals. False-positive and false-negative testing have a large impact on patient care. All members of the healthcare team should be aware of common limitations in testing, such as urine assay false positives with hematuria, false negatives with dilute urine, and more obscure but still very relevant causes of inaccurate testing. Interpreting results that may be false should be undertaken with care to help prevent unnecessary testing and treatment.[29] Effective interprofessional communication is crucial for making timely clinical decisions, enabling all team members to collaborate in sharing relevant findings and coordinating follow-up care. Coordinated care ensures that abnormal results are promptly addressed, referrals are efficiently managed, and patients receive accurate information and support throughout their diagnostic journey. By aligning their roles and responsibilities, healthcare professionals can enhance patient safety, improve clinical outcomes, elevate team performance, and foster a high-performing, patient-centered care environment.
