If doing a blood test for pregnancy you need to be looking specifically for hCG, it does not just show up in other tests. In the case of finding it when checking blood in suspected food posioning, in most cases of persistant nausea in childbearing women, a hCG level is done, to rule out pregnancy or in some cases to confirm it.

When doing bloodwork for a pregnancy test, it is fairly similar to a home pregnancy test, so yes, they must do a specific test for it. Specific proteins that are present when a pregnancy happens are in the bloodstream, and activate protein receptors on the surface of a particular test. This activation is typically displayed by a color in some sort of shape.
If they don't test for pregnancy, they will not find it, but if there is any question of a possibility, they most likely will test for it.

The beginning of pregnancy may be detected in a number of ways, including various pregnancy tests which detect hormones generated by the newly-formed placenta. Clinical blood and urine tests can detect pregnancy as early as 6-8 days after date of conception. Home pregnancy tests are personal urine tests, which normally cannot detect a pregnancy until at least 12-15 days after conception. Both clinical and home tests can only detect the state of pregnancy, and cannot detect the actual date of conception.
When a woman becomes pregnant, the pregnancy hormone (human chorionic gonadotrophin, or hCG) is produced.
An hCG beta blood test as administered at your doctor's office is much more sensitive than an HPT, yields a quantitative result (as opposed to the qualitative "yes" vs. "no" result of an HPT), and can detect pregnancy as early as 10 days after fertilization.
What is hCG?
Human Chorionic Gonadotropin (hCG) is the "pregnancy hormone" that keeps the corpus luteum producing progesterone when conception occurs. It is produced by the placenta during pregnancy and is measured by home pregnancy tests (HPTs). A woman "usually" produces 25 milli-international units per milliliter (mIU/ml) of hCG 10 days after conception. As a general rule, hCG beta numbers should double every two to three days. Accordingly, the concentration of hCG rises rapidly, frequently exceeding 100 mIU/ml by the first missed menstrual period and peaks in the range of 30,000-200,000 mIU/ml by 8-10 weeks into pregnancy. An hCG level of less than 5 mIU/ml generally indicates that one is not pregnant.
The appearance of hCG in urine soon after conception and its subsequent rise in concentration during early gestational growth make it an excellent marker for the early detection of pregnancy. However, if you have been given an hCG injection (Profasi, Pregnyl) to trigger ovulation or to lengthen the luteal phase of your cycle, trace amounts can remain in your system as long as 10 days after your last injection and may give a false positive on a pregnancy test. Two consecutive quantitative hCG beta blood tests can circumvent this problem; if the level increases by the second test, you are likely to be pregnant.

They probably have to be testing for it. But at this day in age, its probably a test they would automatically perform to the blood of any woman of child-bearing age. There are alot of procedures and medications that could cause pregnancy complications, so its probably something they do just to cover their own butts and help prevent lawsuits.

You mean if they just do blood work for something else and you dont ask them to check for pregnancy?
Iam pretty sure they have to test for it. i dont think they send your blood through a battery of tests everytime they take it.
I could be wrong though.

They can't tell if that's not what they're looking for.
