yes...fraternal twins (different ova and different sperm). although it is also possible to generate identical twins I suppose (single ovum and single sperm). I have no idea what the statistics on this are however.
Although if you're *really* asking "can I *force* a fertilized ovum to split into two and generate a set of identical twins?" then I would have to say "Not likely".
Yes, an ovum can be forced to split. The above information is outdated.

using the scientific method
By using tensile test.
Depending on what method the lab is is using to test your urine, you could test positive for amphetamines if you take pseudoephedrine (Sudafed)

what is test-retest method
This is possible only by using spectrometric method of analysis.
Its you using the scientific method, where you gather an observation, form a hypothesis, test out your hypothesis, and then analyze you conclusions

You form a hypothesis then u test it

No. But the result may be fainter. Do another test.
No there, is no specific blood test to check for twins, although higher than normal HCG levels in a blood test may be because of twins, although it is no where near accurate for predicting a twin pregnancy.

Assuming there's no question the babies are identical twins then, no. A paternity test on one will answer the question. However if they are fraternal twins (not identical) then, yes, each must be tested.
In all seriousness: Find out how long whatever it is stays in your system and quit using for that length of time before the test. It is the best method.
The scientific method requires you to have a hypothesis and test it systematically in a way that can be repeated by others. Experiments that do not follow this system are not using the scientific method.
No, if anything twins give a higher hormone level. 21 years ago while pregnant with twins I had a positive test on the day my period was due.
Sickle cell anemia is detected by performing a blood test using a method called high-performance liquid chromatography (HPLC).
There is no such thing as "semi-identical" twins. If fraternal twins each take a paternity test, only the real father would show up as the father.
