Question 1

how accurate are online scan pregnancy test?

Accepted Answer

Urine test is better: Testing one's urine is so simple and so accurate that there is no reason to bother with an online survey. An online test cannot give a definite answer (it has no sample of one's blood or urine), so it can only make a guess (hopefully and educated guess).

Question 2

how accurate are ultrasound scans in pregnancy?

Accepted Answer

Depends: The precision of an ultrasound depends somewhat on the equipment, the technician, the interpreter & the reason for study. If the scan is done to verify the placental location, fetal position & head size(to verify dates), simple equipment works ok. Specific things about baby like heart anatomy, facial features and the like, require a skilled technician using special equipment & interpretation.

Question 3

is my 6 week pregnancy scan more accurate or my 12 week scan to when i conseived?

Accepted Answer

The earlier the bett: Although, earlier scans appear to be more accurate, the difference between 6 and 12 weeks should not be striking.

Question 4

do you really need to know your lmp or is a dating scan an accurate enough way to see how far gone you are in pregnancy?

Accepted Answer

US is enough: An early dating scan in the first trimester of pregnancy is quite accurate for determining how far along someone is in her pregnancy.  It is especially useful for those who are uncertain of their LMP or who have irregular cycles.  While not exact, the dating scan is usually accurate within a few days of the actual gestational age.

Question 5

how accurate is a dating scan performed at 13 weeks pregnancy?

Accepted Answer

Should be ok: Dating ultrasound scans have good accuracy at 8-11 weeks, so one done at 13 weeks should still be reliable. Dates by ultrasound are always estimates.

Question 6

are ultrasounds done at 13 weeks pregnant accurate? what is the margin error of dating scans performed at this stage of the pregnancy?

Accepted Answer

Yes, fairly accurate: The margin of error on a dating scan at 13 weeks is approximately 7 days.

Question 7

in early pregnancy lmp or ultrasound is accurate? scan showing 4w6d and as per lmp it is 5w2d, saw sac and tiny yolk sac. need to worry? :(:(reg perds

Accepted Answer

3 day difference: All tests have error bands.  You report a three day difference in two methods of estimating your fetus' gestational age. The key word in that sentence was estimating. Try to relax and enjoy your pregnancy and future baby.

Question 8

how accurate it is counting pregnancy weeks using the first day of your last period?again can i get pregnant if i was on my periods on 19 feb 2021 and had unprotected sex on the 23 when i was finishing  my periods?will a scan tell my pregnancy weeks?

Question 9

had 3 ultrasound scans 1 @ 3 week to early to see hcg 32 , 7 week edd 17/feb/22, 12 week scan edd 17/feb/22 and 20 week edd 17/feb/22, how accurate is this and would i of conceived end of april? also does hcg 32 suggest early pregnancy?

Accepted Answer

: A positive HCG at "three weeks of pregnancy" indicates early pregnancy, and the low level is consistent with ovulation/pregnancy onset 8-10 days prior to this lab result.  Determination of actual ovulation and pregnancy onset is not possible, since pregnancy is possible by intercourse 2-3 days  prior to ovulation, and may occur as late as 2-4 days after ovulation.

Question 10

how early in pregnancy can you have a scan?

Accepted Answer

Depends on purpose: If the goal is to look at baby for seeing normal fetal anatomy, the earliest would be 18 weeks. This allows the m ajor organ systems to be formed to the point of being able to be evaluated. Before 18 weeks the heart has not finished forming and therefore a scan performed prior to this date does not really look at the normally formed fetal heart but a precursor.
