Lab Orders that Cannot Reach the Lab

The In-Patient Phlebotomy Team will not receive orders to draw a patient’s blood if orders are entered in MIS under any of the following conditions:

  • STAT collected
  • Patient has a Central Line Flag
  • Patient’s location in MIS at the time the order is placed is a unit that phlebotomy does not collect (OR, ER, SICU, MICU, NNICU, PICU etc.). 

 The In-Patient Phlebotomy Team does not perform STAT draws or draw from patients who have a Central Line. 

Maternal/Fetal Triple Testing 

The acceptable Medical Laboratories request form for TRIPLE testing of pregnant women has a revision date on the bottom left of the page of 4/99.  If you have an older version of the form please contact Lynne Foster of Client Services at 434-924-5172 to have them replaced with the current form. 

When completing the Medical Laboratories request form for TRIPLE testing you are required to indicate each test separately (AFP, hCG, Estriol) if you desire the entire panel to be performed. 

CMV Antigenemia 

All blood submitted for Cytomegalovirus (CMV) Antigenemia analysis must be collected in Yellow (ACD solution A) or 7ml Lavender top tubes. Please note this is a change back to the old collection requirements. 

Specimens submitted on Fridays must be received in the laboratory no later than 1:00 PM due to sample stability considerations.

Think Pink for the Blood Bank

Remember, when drawing a sample in a plastic tube for a blood bank request, the only acceptable tube is the PINK top.  Please do not substitute the plastic purple top tube.  The PINK top tube is the only one that is FDA approved for blood bank testing and has been validated for use by the UVA Medical Laboratories.  Due to these restrictions, the blood bank staff will reject any purple top plastic tubes and request a redraw.

Arterial Blood Gases and Delivery Through the Tube System 

ABG samples that are sent directly to the Core Laboratory using the pneumatic tube system do not need to be submitted on ice.  There is no harm to the specimen when kept at room temperature for up to 20 minutes.

Antimicrobial Susceptibility Profiles 

The Antimicrobial Susceptibility Profiles for 2000 are available for distribution in the form of pocket cards.  If you would like cards for yourself and/or an area, please contact Heather Proctor in Clinical Microbiology at 4-8059.
