Accuracy of a Scan?

I'm guessing by scan that means ultrasound. And yes, that should be able to tell u if ur pregnant. Good luck

I kno this iz gona sound like a right daft question but is there any chance that the scan wil show i'm not when I am realy? Or is that impossible

If you are getting an ultrasound, if there is a baby in there, it will find it. If nothing is found, then you aren't pregnant, the ultrasound is very accurate.

And they'll probably do an internal scan so those are super accurate! Just a warning....They're gonna stick it up your vagina, it's a lil uncomfortable but they can see the smallest sac by doiing one!

Yes, I forgot to mention what lil blaze mentioned haha. Your probably going to get a sonogram rather than an ultrasound (the ultrasound is through your belly). The sonogram is this long rod thing that is put in your vagina. Once its in there, I didnt really notice it, except for the fact that they kept moving it around and sometimes it felt like they were going to freaking jab the thing through my vagina wall or something haha. But I also happen to be very tender down there.

It wont be that big of a deal. How far along are you expected to be if you are indeed pregnant?

U guys are all scareing me even more now... All my doctor said was that she'l book me in for a scan so shouldn't that mean just a normal belly scan to detect a pregnancy, and how many weeks I am and make sure babys ok. Why would I need a internal scan and that other thing a sonogram or watever becuz im sooo sure they didn't do these tests before so what if all these new tests cause more harm than good and would I have to have them (why is it sooo important). Everyone here givs more support than doctors these days, my doctor never even thought to let me know what scan she was bookin me in for :roll: so fanx all u guys becuz if u lot didn't post id b mental by now-i mean the way im stresin just carnt help it tho.

No don't be scared, I didn't have a belly u/s till I was 12 weeks along at my 5 week, and 9 week u/s they did it vaginally cause the stomach one doesn't really detect anythign till later on.

And sonogram/ultrasound/scan all pretty much mean the same thing it's not 3 diff tests. Just they do internal when it's earlier.

Sonagrams are uncofortable but hteir not that bad. They still might do one later down the road just to check your cervix and everything but its a normal prosedure. The u/s isn't that bad but the gel is cold and I would definatly fill up your blatter (nothing worse then a catider). Anyway gl!! Let us know how many weeks!!

Fanx guys for that and yeh if I am pregnant I will let u all know how many weeks I am. But for the gossip my doctor reckons im almost 3 mths if I am (thats becuz from the mornin afta pil that I tuk my doctor said she thinks it could not have worked) but I think im about 4/5weeks. (im sayin this becuz my last period was on time and normal afta the mornin afta so I think it did work but just before my 2nd period was due my bf was mesin round an he touched me when I think he had it on hiz hands. (now ur probly wonderin why he did thiz but thas becuz he wonted to get me up the duf when id always make him use a condom.

Hi,

ultrasound/ultrasonography/sonography has all the same meaning – the use of high frequency sound waves which are emitted from the ultrasound probe. These sound waves are absorbed by the tissue under investigation and reflected back to create an image.

In the first trimester the practitioner may use two methods of ultrasound imaging –

1) trans-abdominal – where the ultrasound transducer is placed on the abdomen

2) trans-vaginal ultrasound – where the ultrasound probe is placed within the vagina.
Transvaginal scanning can be valuable in early pregnancy (before 12 weeks), because the uterus as not yet inclined out of the pelvis and because the transducer probe is placed next to the women’s cervix – and so is closer to the small pregnancy which produces a more accurate and detailed image than the trans-abdominal scan.

Ultrasound is highly accurate in the detection of pregnancy. However, the accuracy of the scan can depend on several factors –
e.G. A very early pregnant it can sometimes be difficult to visualise because it is so small – so occasionally the pregnancy may go undiagnosed. The baby’s heart beat can also usually be detected approximately between the 6th to 7th weeks of pregnancy.

To sad-eyes:transvaginal scanning can be valuable in early pregnancy (before 12 weeks), because the uterus as not yet inclined out of the pelvis and because the transducer probe is placed next to the women’s cervix – and so is closer to the small pregnancy which produces a more accurate and detailed image than the trans-abdominal scan.

Does that mean that if im more than 12 weeks becuz theres a chance I am, that it would not be a good thing to have the transvaginal one done???

And u said also that it may not show in early pregnancy so what if it doesnt and ive alredy had a blood test+urine test done. Do u think I should go to my doctors and ask to be on the prenatal vits and folic acid becuz I have not even got a date yet for my scan and blood test is not til another few weeks so il be leaving the vits+folic acid til too late won i?

I keep hearing americans here talking about having to get a prescription for pre-natal vits and folic acid. Can't you just buy them in your pharmacy like we do up here??

There is no harm taking the vitamins and folic acid.

As for the vag u/s, if your doc thinks you are further along they will start off with the belly scan if they don't see anything they will go vaginally (well that is what they did for me) and it's not dangerous when you are further along either.

Hi,

if you are more than 12 weeks pregnant then the ultrasonographer will probably not perform a trans-vaginal examination - it will not be needed because the pregnancy will be large enough for the trans-abdominal scan to detect. The ultrasound examination is highly accurate and should detect the pregnancy unless were talking few days to first few weeks of pregnancy.

I am unsure of the accuracy of other diagnostic tests (urine and blood) but I presume that they are testing for the presence of the same hormone - human chorionic gonadotropin which is produced in pregnancy.

Did you have the urine test and the blood test on the same date? I am unsure also whether there are any other factors which can affect the result of these tests, such as time of day which the tests are performed - think that hcg in the urine is highest in the morning, so am unsure as to whether a urine test performed late in the day would affect the result.

I think the spinal cord will be developed by the third month of pregnancy – but you could maybe go to your gp and say that you think that you might be about three months pregnant but you’re unsure you might be less, so you would like to start taking folic acid supplements. Your gp can then advise you which supplements you should take and the dosage required.

Take care.

Hey. No I didnt have the urine test and blood test on same day. The urine one is always best done in the day. I had the blood test a week after. But im not sure if im spose to not eat or drink before I have my next blood test.
And I did sumit realy bad I was on the multivitamins and magnesium tablets till my doctor told me that the signs I was having (spoting and late period) was probly that I am preg and could be 2/3 months. And on them vitamins it says not to have if pregnant. I asked my doc about the folic (not the prenatal vits becuz I only found out about them when I come on eya) and my doc said I don't need them till I kno im pre for sure.

Soz I forgot to say that the urine test is best done 1st thing in the morning like your 1st wee of the day. :)

Dun worry much about the tests n just go along... It is safe and accurate.

Hiya

i wouldn't worry bout the vaginal scan, I think they will only do one if they can't find anything when they do a normal ultrasound!. I had an ultrasound at 6 weeks + 4days, they easily saw the sac and the doc saw a heartbeat, even managed to give me a foto of the scan showing the sac with a little white blob inside which was the embryo, so unless your really early, they should be able find out easily if you are pregnant or not.

Good luck!!
Keep us informed!!
