blood checking

[Peter D. Krevat]

	Dear Avi,

	If I understand you question, yes, I can think of one "blood 
test" off the top of my head which doesn't require anything sharp.  It is 
called Pulse Oxemetry, a test where the oxygen saturation of the blood 
can be evaluated using a small light probe which clips on to the end of a 
finger.  It is not always 100% right, but alot of times it is used in the 
hospital for an easy and non-invasive way to evaluate oxygen saturation.
	I hope this helps.
