1. Requisition requirements:

        All samples submitted to the lab must be submitted by authorized personnel and accompanied by        
        a completed UAMS Cytogenetics Laboratory Chromosome Analysis Request Form and must include:

• Patient name and address
• Accession number
• Date of birth
• Sex of patient
• Name and department of submitting physician and lab
• Clinical information (primary diagnosis, transplant information, etc.)
• Source of specimen
• Date and time specimen collected
• Type of tests requested
   

2. Specimens should be collected under sterile conditions.  Place a hospital or clinic label on the
   specimen container.  Ensure that the container is securely packaged to prevent temperature
   extremes or leakage during transport.
    

3. Specimens requiring an anticoagulant must be submitted in sodium heparin. 
   If a Vacutainer is used, gently invert the tube five to ten times; do not shake. 
   Lithium heparin is contraindicated.
    

4. If UAMS Cytogenetics transport medium is recommended but not available, other
   sterile tissue culture media may be substituted.
    

5. Deliver specimens the day of collection at room temperature accompanied by a completed
   UAMS Cytogenetics Laboratory Chromosome Analysis Request form. 
   Specimens collected within UAMS should be delivered to the UAMS Clinical Laboratory;
   specimens collected outside the institution should be delivered directly to the Cytogenetics Laboratory. 

   EXCEPTION:  Pleural effusion specimens optimally should be delivered within one hour of collection.

6. Specimens should be transported at room temperature.  Do not freeze or send samples on ice.
    

7. Specimens collected after hours should be kept at room temperature and sent to the
   UAMS Clinical Laboratory. 
   
   EXCEPTION: Solid tissue specimens, if not received the same day as collection, should be refrigerated
   to inhibit potential bacterial growth.
    

8. UAMS Cytogenetic Transport Media contains 6cc of sterile supplemented RPMI media and
   12µl sodium heparin (1000 U.S.P.)
