Are you sure you had a test for blood sugars, this isn’t part of the routine tests, however during covid some trusts did a test for blood sugars at booking for women at risk of gestational diabetes instead if the usual test they do for these women later in pregnancy. Otherwise blood sugars may be done if you had glucose in your urine but it isn’t part of the standard screening tests.
The standard screening tests taken (if consented by woman) at booking in England for all women are
Full blood count - looks at Hb (potential anaemia)
- white cell count - can indicate infection
- platelets - potential clotting problems
indication as to whether you might be a carrier for the gene for sickle cell or thalassaemia (combined with ethnicity)
Blood group and blood cell antibodies
Hepatitis B
HIV
Syphillis
Offer of combined screening test to give indication of risk is Down’s syndrome, Edward’s and Patau’s syndrome - involving measurement of back or baby’s neck on scan (nuchal fold) and blood test after the scan - can only be undertaken if measurements correlate with baby being between 11-14 weeks gestation at the scan, if baby found to be smaller then booked another scan and if bigger offered the quad blood test (just for Down’s) after 16 weeks
of risk comes back as more that 1:150 then NIPT blood test offered which gives a 70-90+%accuracy of whether baby affected by Edward’s, Patau’s or Downs (can have this test done privately from 10 weeks)
Alternatively will be offered opportunity to go straight for CVS/amnio which will tell you with 99.9% certainty if baby affected but does carry a small risk of miscarriage as obviously invasive test
Usually also MSU Culture in lab - to check for urinary tract infection
The vast majority of women usually consent to all the usual screening so would be unusual for it not to be documented somewhere if the midwife had understood you had declined the test. I would of also thought they would of just confirmed with you at the scan also that you had declined the combined screening if that was there understanding so would usually be picked up then if the midwife had forgotten to mention it at booking
