  ABSTRACT: Objective: To examine the correlation between plasma hCG results obtained with the new i-STAT® hCG point of care test with those concomitantly obtained from the central hospital laboratory utilizing the same patient samples. Methods: Prospective cross-sectional laboratory test evaluation. We compared plasma hCG results obtained with the i-STAT® hCG test (Abbott Point of Care, Princeton, NJ, USA) with Architect Ci8200 (Abbott Laboratories, Abbott Park, IL, USA). We also calculated the total coefficient of variation (CV) for the i-STAT® method. Results: The two methods showed a good linear correlation (R2 = 0.994; slope 1.03) and CV for the i-STAT® method was 2.1% - 5.2%. Conclusion: We suggest that the i-STAT® hCG blood assay could be used as a complement to urine hCG assays in clinical situations when rapid test results are needed and urine is not available.
