It is possible to present hcg hormon in non pregnant women?if yes so how it's possible and from where hcg secreted in non pregnant women?i saw the non pregnant women beta hcg blood test report the hcg level 0.53 it's normal or possible in nonpregnt ?

Pituitary gland also makes HCG. Your level of 0.53 is well below that seen in pregnancy. A level below 5 excludes pregnancy. Level above 30 is diagnostic of pregnancy. For a level between 5-30, the test should be repeated in 4-5 days. Get HPV vaccine. Wish you good health! Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/safer-sex-guidelines
