Connect Sign InIdentifying the Pregnant Patient: There's More to Know than 'Yes' or 'No'
Human chorionic gonadotropin (hCG) is used as a biomarker to determine a woman’s pregnancy status. The detection of hCG is commonly done by the use of qualitative hCG tests using urine or serum. While both sample types can be used, urine is often preferred due to its ability to be analyzed at the point-of-care. Urine hCG testing is plagued by several limitations yet these are often not appreciated by clinical care providers and laboratorians. This presentation will describe the limitations of qualitative urine and serum hCG tests and explain the causes of erroneous results. It will also describe the effect that qualitative hCG tests have on turnaround time and patient length of stay.
