How long has someone been pregnant with an HCG level of 287?

An HCG result of 287U/L corresponds to approximately 1-2 weeks of gestation. If the HCG result is 287IU/ml, it is generally considered to be 4-5 weeks of gestation. HCG is a hormone unique to pregnancy, primarily produced by trophoblastic cells during gestation. In the early stages of pregnancy, as the embryo grows and develops rapidly, the concentration of HCG in the blood also increases rapidly. During the 1-2 weeks of gestation, the concentration of HCG can reach 50-500U/L. Therefore, an HCG result of 287U/L suggests a gestation period of 1-2 weeks. Generally, during the 4-5 weeks of gestation, HCG typically ranges from 75-2600IU/ml. Hence, an HCG value of 287IU/ml indicates a gestation period of 4-5 weeks. At this stage, an ultrasound usually cannot detect a visible gestational sac, and it is not possible to assess embryonic development or detect ectopic pregnancy. It is important to rest adequately and follow medical advice for timely follow-up examinations. If there is suspicion of abnormal embryonic development or implantation site, a follow-up examination can be conducted every other day. If HCG doubles, it usually indicates normal embryonic development. Slow rising may indicate ectopic pregnancy or congenital developmental abnormality.
