I reviewed the information you provided and the data in the datasets, and I'm giving some summaries based on the Stata data below:
1) The sample is all men and women age 35-64 in the half of households that were selected for the men's questionnaire.
. tab hv104 if hv027==1 & hv105>=35 & hv105<= 64,m
sex of |
household |
member | Freq. Percent Cum.
------------+-----------------------------------
male | 2,163 45.57 45.57
female | 2,584 54.43 100.00
------------+-----------------------------------
Total | 4,747 100.00
From this you can see that 2,584 women and 2,163 men were eligible for these tests. These numbers are unweighted as they are the actual numbers tested in the survey.
2) From these cases, a total of 3,634 (2,085 women and 1,530 men) granted consent for blood pressure testing, and 3,316 (1,937 women and 1,379 men) granted consent for blood glucose testing (unweighted again). These numbers translated into the percentages as shown below.

3) The numbers presented in the coverage of testing are unweighted numbers as they related to the testing in the survey, and not to estimates for the population. The numbers in table 17.4.1 and 17.4.2, and in 17.7.1 and 17.7.2 are weighted as the percentage estimates are for the population. These tables also include slightly less cases than above as some cases had out of range values and are excluded from the tables see the extra conditions used below.
. tab hv104 if sh333 == 1 & sh335aa >= 30 & sh335aa <= 300 & sh335ab >= 0 & sh335ab <= 160 [iw=hv005/1000000], m

I hope this helps explain the differences that you see.
