i have also read this in the RI law guide. does this mean that blood extracted for medical purposes can not be used against me, seeing how i did not consent to any test?

(c) In any criminal prosecution for a violation of subsection (a) of this section, evidence as to the amount of intoxicating liquor, toluene, or any controlled substance as defined in chapter 28 of title 21, or any combination of these, in the defendant's blood at the time alleged as shown by a chemical analysis of the defendant's breath, blood, or urine or other bodily substance shall be admissible and competent, provided that evidence is presented that the following conditions have been complied with:

(1) The defendant has consented to the taking of the test upon which the analysis is made. Evidence that the defendant had refused to submit to the test shall not be admissible unless the defendant elects to testify.
