Doctors instead look to see if hCG levels double every 48 to 72 hours from whatever level they started at. They look for this in the initial weeks of pregnancy, as it's normal for hCG levels to peak around 8 to 11 weeks' gestation, then decrease, and level off thereafter.
If your hCG levels are low, it is likely that another test will be performed in a few days to confirm if levels are increasing or not.

Some women simply have higher levels. If a woman has high hCG levels, it could point to twins or triplets, though only a scan can confirm this. Sometimes, above-average levels of hCG indicate a higher chance of Down syndrome. A doctor can use blood tests and scans to check. One medical concern about higher levels of hCG is that they may indicate gestational trophoblastic disease GTD.
GTD can occur during or after pregnancy. It causes abnormal cells to grow in the uterus. Some can be cancerous, though most are benign. Treatment depends on the mass of cells and whether it is cancerous or benign. To remove the mass, the doctor may recommend dilation and curettage, which involves sucking away the mass with a surgical vacuum and gently scraping away any remaining abnormal cells. Or, a doctor may recommend a hysterectomy, to remove the uterus.
After the removal, a person may need chemotherapy or other treatment. This may be more likely if hCG levels remain high. High hCG levels may also indicate preeclampsia, a pregnancy-linked condition that involves swelling and a sudden rise in blood pressure.
In a study , for example, researchers found that hCG levels were significantly increased in women with severe preeclampsia.
