valoare scazuta Beta hCG

Tocmai mi-am luat rezultatul la tripu test si beta hCG mi-a iesit 3157 iar valorile normale intre 11 si 16 saptamani este 6140-103000 eu facandu-mi testul la 14 saptamani imediat dupa ecografie. La ecograf pliul nucal a fost de 1.8 mm.
Stie cineva ce poate sa insemne?

irlandeza spune:

In cate sapt. esti? Acest rezultat e pt. o sarcina mica, de 6 sapt. Esti sigura ca nu au gresit ? Si eco a iesit OK ? Citeste mai jos, mai multe info.


Key things to remember about hCG levels:
About 85% of normal pregnancies will have the hCG level double every 48 - 72 hours. As you get further along into pregnancy and the hCG level gets higher, the time it takes to double can increase to about every 96 hours.
Caution must be used in making too much of hCG numbers. A normal pregnancy may have low hCG levels and deliver a perfectly healthy baby. The results on an ultrasound after 5 - 6 weeks gestation are much more accurate than using hCG numbers.
An hCG level of less than 5mIU/ml is considered negative for pregnancy, and anything above 25mIU/ml is considered positive for pregnancy.
hCG is measured in milli-international units per milliliter (mIU/ml).
A transvaginal ultrasound should be able to see at least a gestational sac once the hCG levels have reached between 1,000 - 2,000mIU/ml. Because levels can differentiate so much and conception dating can be wrong, a diagnosis should not be made by ultrasound findings until the level has reached at least 2,000.
A single hCG reading is not enough information for most diagnoses. When there is a question regarding the health of the pregnancy, multiple testings of hCG done a couple of days apart give a more accurate look at assessing the situation.
hCG levels should not be used to date a pregnancy since these numbers can vary so widely.
There are two common types of hCG tests. A qualitative hCG test just looks to see if hCG is present in the blood. A quantitative hCG test (or beta hCG) measures the amount of hCG actually present in the blood.
Guideline to hCG levels during pregnancy:
hCG levels in weeks from LMP (gestational age)* :

3 weeks LMP: 5 - 50 mIU/ml
4 weeks LMP: 5 - 426 mIU/ml
5 weeks LMP: 18 - 7,340 mIU/ml
6 weeks LMP: 1,080 - 56,500 mIU/ml
7 - 8 weeks LMP: 7, 650 - 229,000 mIU/ml
9 - 12 weeks LMP: 25,700 - 288,000 mIU/ml
13 - 16 weeks LMP: 13,300 - 254,000 mIU/ml
17 - 24 weeks LMP: 4,060 - 165,400 mIU/ml
25 - 40 weeks LMP: 3,640 - 117,000 mIU/ml
Non-pregnant females: <5.0 mIU/ml
Postmenopausal: <9.5 mIU/ml
* These numbers are just a GUIDELINE-- every woman’s level of hCG can rise differently. It is not necessarily the level that matters but rather the change in the level.

What can a low hCG level mean?
A low hCG level can mean any number of things and should be re-tested within 48-72 hours to see how the level is changing. A low hCG level could indicate:

Miscalculation of pregnancy dating
Possible miscarriage or blighted ovum
Ectopic pregnancy
What can a high hCG level mean?
A high level of hCG can also mean a number of things and should be re-tested within 48-72 hours to evaluate changes in the level. A high hCG level can indicate:

Miscalculation of pregnancy dating
Molar pregnancy
Multiple pregnancy
Should my hCG level be checked routinely?
It is not common for doctors to normally re-check your hCG levels unless you are showing signs of a possible problem. A health care provider may re-check your levels if you are bleeding, having severe cramping or have a history of miscarriage.

What can I expect of my hCG levels after a pregnancy loss?
Most women can expect their levels to return to a non-pregnant range about 4 - 6 weeks after a pregnancy loss has occurred. This can differentiate by how the loss occurred (spontaneous miscarriage, D & C procedure, abortion, natural delivery) and how high the levels were at the time of the loss. Health care providers usually will continue to test hCG levels after a pregnancy loss to ensure they return back to <5.0

Can anything interfere with my hCG levels?
Nothing should interfere with an hCG level except medications that contain hCG. These medications are often used in fertility treatments, and your health care provider should advise you on how they may affect a test. All other medications such as antibiotics, pain relievers, contraception or other hormone medications should not have any effect on a test that measures hCG.
