Hcg levels and pregnancy dating
No considerable differences were found between RRs calculated in the general population or in uncomplicated pregnancies only.
Maternal smoking, BMI, parity, ethnicity, fetal gender, placental weight and hyperemesis gravidarum symptoms were associated with total h CG.
We provide gestational RRs for total h CG and show that total h CG values and RR cut-offs during pregnancy vary depending on pregnancy dating methodology.
This is likely due to the influence of h CG on embryonic growth, suggesting that ultrasound based pregnancy dating might be less reliable in women with high/low h CG levels.
These are used to compare with other pregnancies on percentile charts.
Gestational age specific RRs using ‘ultrasound derived gestational age’ (US RRs) were calculated and compared with ‘last menstrual period derived gestational age’ (LMP RRs) and a model-based RR.
The Fundal height measurement is an old an quick way to check baby is growing at the right rate.
At most visits your pregnancy weight gain is checked as too little or too much weight gain may cause problems at a later stage.
