I'm sorry to barge in on this thread. I don't know anything about lab equipment, but I have a question for all of you. I had been going to one lab to get a stat quantitative hcg test and it was always reported as an exact number. However, I went to a different lab and they reported it as "greater than 5,000." Have you ever heard of that? Does that mean they just stopped running it after 5,000? My nurse is perplexed, but said they may not have diluted it down properly. It just about gave me a heart attack. It seems like you lab insiders may be able to solve my mystery. Thank you ahead of time.
