a

Pregnancy Test: Positive vs Negative Results

here we have our droppers and they

contain our urine sample we use the

droppers that came with the pregnancy

test to withdrawal the urine in this top

dropper

we have urine that contains HCG and how

I know that is because it's my urine and

I'm pregnant

this bottom dropper contains urine that

does not have HCG in it it comes from my

husband so he shouldn't have HCG in his

urine so what we're gonna do is we're

gonna add three drops of urine to each

test so add to this top one this is the

urine that has the HCG so 1 2 3 and then

wad drop here 1 2 3 and we're gonna let

that go for 3 minutes cuz for this

particular test they say to wait 3

minutes to read the results but don't

read the results after 5 minutes because

they won't be valid

you

so it's been three minutes now we're

going to interpret our results so as you

can see here in these tests we have a

line in both of the control areas this

tells us we added enough urine and that

this test is working however in this

pregnancy test here on the top there is

a line in the test area so it's positive

which tells us that it detected HCG in

the urine however here on the bottom

this bottom pregnancy test there is no

line in this test area so it is negative

it tells us that it did not detect HCG

in that urine sample
