Introduction

A complete blood count (CBC) can initially assess the presence of ectopic pregnancy by measuring the levels of human chorionic gonadotropin (hCG), but it cannot provide a definitive diagnosis. Therefore, if abnormal results are found through CBC, further examinations such as ultrasound, laparoscopy, or posterior vaginal fornix puncture should be conducted under a doctor's guidance to accurately determine whether an ectopic pregnancy exists.

Generally, a blood test refers to a routine blood examination. Ectopic pregnancy can be preliminarily diagnosed through routine blood testing, although a definitive diagnosis usually cannot be made solely by this method. If there are any concerns, timely medical consultation is recommended. Detailed analysis is as follows:

Routine blood testing primarily involves drawing blood for analysis and can be used to measure the level of human chorionic gonadotropin (hCG). If an ectopic pregnancy is present, the hCG levels may continuously rise and exceed the normal range. Therefore, a routine blood test can provide a preliminary indication of whether an ectopic pregnancy exists.

However, a routine blood test alone cannot accurately confirm the presence of an ectopic pregnancy, as it does not allow observation of the uterine structure or provide information regarding embryo implantation. If abnormalities are detected through routine blood testing, further examinations such as ultrasound, laparoscopy, or posterior vaginal fornix puncture should be conducted under a doctor's guidance.

Routine blood testing carries certain risks; therefore, it is recommended to undergo the test under the guidance of a qualified physician. Additionally, adequate rest is necessary after the examination to avoid excessive fatigue.

What does it mean if the gestational sac cannot be seen at 42 days of pregnancy?

In general, the absence of a gestational sac at 42 days of pregnancy may be caused by miscalculation of gestational age, delayed embryo implantation, ectopic pregnancy, embryonic arrest, polycystic ovary syndrome (PCOS), or other reasons. If any discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. In daily life, women should keep track of their menstrual cycles to accurately estimate gestational age, and avoid exposure to harmful substances when trying to conceive or during early pregnancy.

What causes lower back pain and brown discharge during pregnancy?

Back pain during pregnancy accompanied by brown discharge may be caused by hormonal changes, uterine enlargement, implantation bleeding, threatened miscarriage, ectopic pregnancy, or cervicitis. Symptoms can be improved through rest, regulation, and medication. If the discharge increases, back pain worsens, or is accompanied by abdominal pain, prompt medical attention is necessary. Hormonal changes during pregnancy cause ligament relaxation, while uterine enlargement may compress the lumbosacral area.

When should high-risk pregnant women begin evaluation of fetal well-being?

If high-risk factors are pre-existing medical conditions (such as hypertension or diabetes) or maternal age over 35, assessment usually begins around 12 weeks of gestation. At this time, fetal development can be evaluated via ultrasound, and hormone levels can be monitored through blood tests, allowing early detection of potential problems affecting fetal health and providing time for subsequent interventions.
