Study to Investigate Blood Samples Drawn With the HemoIV System

The goal of this study is to compare blood drawn using a device called HemoIV to standard-of-care blood drawn from a vein in the arm or from an IV catheter. The HemoIV is a device that is attached to an IV line. This device allows for blood to be drawn while a patient is receiving IV fluids. The main questions it aims to answer are: * Will the HemoIV device allow blood to be drawn without having to stop IV fluids? * Will the HemoIV device provide the same laboratory results as blood draws done by current standard practice? Participants will: * Receive standard medical procedures and/or treatment; * Have a HemoIV device inserted into their IV line in one arm; * Have an blood drawn twice from the HemoIV and from an IV line or needle stick from a vein in the other arm. The second blood draw will be done about 8-22 hours after the first blood draw; * Have the device removed after the second blood draw; * Receive a phone call about 8 days later to see how you are doing.
