The senior member of staff walked in, didn't ask us any questions, how far along we were, any kind of past history, or anything like this, didn't even look at the notes, put the scanner on and kind of after scanning around for a bit, took the scanner off and started saying, 'Well, why have you come this early?

So if you have a blood test at 14 weeks, the results would be of no help if a scan later revealed you were actually 16 weeks pregnant when the blood was taken. The main reason for the scan is to work out how many weeks pregnant you are, and to estimate your due date.
If the blood test is taken too early because your dates are wrong, this might lead to you being given a high risk factor when, in fact, your baby is developing normally. The length of your pregnancy is calculated from the first day of your last menstrual period (LMP), even though you don't actually conceive until 14 days after your LMP, and later than this if your cycle is longer than 28 days.
