Answer: It depends on what information is needed. Hair tests can give a longer history of drug use than urine or blood. Urine tests can detect certain substances from anywhere to several hours or up to a month after use. Blood tests show what substances are currently active in the bloodstream and in what amount.
Also, there are many types of urine drug tests, some more accurate than others. Most of the urine tests that are used for employment and for law enforcement (including court officer testing) have a a larger margin for false negative and false positive than is common knowledge.
Answer: Yes, as long as there is a pregnancy, anywhere in the body, a urine based pregnancy test will prove possitive, simply because the body is producing a hormone that will help your baby grow, regardless of where it is placed.But, if a tubal pregnancy is in place, the embryo should be removed because the tube bursts and causes extream pain and/or death by loss of blood if not treated soon enough.
Answer: Many women report a slight bleed when their period is due. It is not unheard of, but is rather uncommon. An "early" pregnancy test from the pharmacy should give you a positive result now (ie when your period is due). But most test need about 7 days more to give a positive result.

Answer: Yes and No, I had an ectopic pregnancy and we found it because my HCG levels in the blood test were not doubling like they were suppose to. But it was my 3rd ultrasound, ( I went every week for one after I found out I was pregnant and we were watching my HCG levels) and we finally found out that yes it was in my tube.So not one blood test will tell you if it is ectopic or not.. but a series of them will.
Answer: Occult blood indicates the presence of red blood cells which are normally not seen in urine. This usually indicates either physical trauma to the spleen or lower abdomen, or urinary tract infections which allow the passage of these cellular elements. Note that taking anticoagulants like Coumadin Amy also cause this.
