This test is qualitative with results reported as positive, negative or borderline: A Positive result is given when the hCG is ≥ 25 IU/L A Negative result is given when the hCG is ≤ 5 IU/L A Borderline result is given when the hCG is between 5 – 25 IU/L.
What does borderline pregnancy result mean?
A borderline result is generated by some assays when the hCG level is between 5 and 25 mIU/mL. Samples reported as borderline are considered indeterminate, and clinicians should request a repeat test within 48 to 72 hours or obtain a quantitative serum hCG.
What hCG level confirms pregnancy?
An hCG level of less than 5 mIU/mL is considered negative for pregnancy, and anything above 25 mIU/mL is considered positive for pregnancy. An hCG level between 6 and 24 mIU/mL is considered a grey area, and you’ll likely need to be retested to see if your levels rise to confirm a pregnancy.
What was your hCG level at 4 weeks?
At 4 weeks pregnant, your hCG levels can range from about 10 to 708 mIU/mL.
Which hCG level is positive cutoff point for pregnancy?
1) suggests that an HCG value of 145 IU/l emerged as the most suitable cutoff point to predict viable pregnancy with 81% sensitivity and 60% specificity (Fig. 1). At HCG value of 145 IU/l, the positive predictive value (PPV) for viable pregnancy was 70% and the negative predictive value (NPV) was 83%.
What should hCG levels be at 5 weeks?
Typical hCG Results
5 weeks: 18 – 7,340 mIU/ml. 6 weeks: 1,080 – 56,500 mIU/ml. 7 – 8 weeks: 7, 650 – 229,000 mIU/ml. 9 – 12 weeks: 25,700 – 288,000 mIU/ml.
What does hCG less than 2 mean?
beta hcg level of less than 2 is indicative of non pregnant status… you are not pregnant.
What is a positive hCG test?
A positive beta hCG levels means that you are pregnant. The hCG level depends on how far along a woman is in her pregnancy. A positive beta human chorionic gonadotropin (hCG) level usually means that you are pregnant. Pregnancy tests detect the hCG hormone in the blood and urine.
What causes low hCG levels in early pregnancy?
A low hCG level can mean your pregnancy date was miscalculated and you’re not as far along as you had thought. Further testing would be needed to determine the cause, which may or may not include a miscarriage, a blighted ovum, or an ectopic pregnancy.
What is the hCG level for twins?
You could have twins, but you can’t really tell from the serum hCG value alone. At 18 DPO the serum hCG for singletons is normally between about 70 and 750 mIU/mL, and for twins, it can be between 200 and about 1750 mIU/ml.
What is the hCG level for twins at 4 weeks?
(Spoiler alert: While higher levels of hCG can indicate twin pregnancy, it is by no means definitive. You’re going to want to get an ultrasound to know for sure.)
|Weeks from last menstrual period||Normal hCG levels (mIU/mL)|
Should you see a sac at 4 weeks?
Gestational Sac, Yolk Sac and Fetal Pole
The gestational sac may be recognized as early as 4 weeks and 1 day from the last menstrual period and should always be seen after 4 weeks and 4 days. Its diameter when first seen is about 2 mm and the normal sac increases in size to measure 5–6 mm at 5 weeks.
How far along am I based on hCG levels?
HCG chart: hCG levels by week
|Number of weeks since last period||hCG levels in mIU/ml|
|5||18 to 7340|
|6||1,080 to 56,500|
|7 to 8||7,650 to 229,000|
|9 to 12||25,700 to 288,000|
Can a woman have low hCG levels and still be pregnant?
Even if a complication associated with low hCG levels occurs, such as a miscarriage or an ectopic pregnancy, this does not mean that someone will be unable to get pregnant again or that their fertility is compromised. A successful pregnancy is still possible with low hCG levels.
What level is hCG at implantation?
Implantation happens as early as 6 days after ovulation/fertilization (usually about 9 days after ovulation), so blood hCG can be found as early as 8-9 days after ovulation/fertilization. Pregnant women usually attain blood serum concentrations of at least 10-50 mIU/cc in the 7-8 days following implantation.
Can your hCG levels go up and not be pregnant?
An elevated β-hCG in the absence of viable pregnancy can occur for multiple reasons and has a broad differential diagnosis including miscarriage, ectopic pregnancy, pituitary hCG production, trophoblastic disease and phantom hCG.
