That "friend" was, according to the article I read, Sarah, sister of Mark Hacking. She may have also told somebody else. Who knows?
Did the report you read/heard specifically state that Lori had not seen a doctor for confirmation of her test result?
Home pregnancy tests can vary quite a bit in reliability, depending on which one is used and the characteristics of the user. From what I've heard, the lion's share of error occurs for false negatives, ie. the user is pregnant and the test says she isn't. That would not apply to Lori.
I have heard the in home test kies often give a false-positive result.
I heard some years ago, there was a test done for
these kits, using elderly ladies and it came out
50/50. Some kit results said they were pregnant.
