- Biochemistry including complete blood count, liver function tests (ALT, AST), blood urea nitrogen, creatinine, and serum total calcium. Participants will undergo venipuncture by a LifeLabs phlebotomist (letter of support attached). A 3 business day turnaround is anticipated for results. Participants with values within normal limits will continue on to enrollment. By this stage of recruitment, participants with any known health conditions/medications suspected to interfere with study outcomes will have been screened out, therefore it is anticipated that most will have values within normal limits.
