Collect

Amniotic Fluid (20-25mL STERILE) in 15mL Sterile Tubes.

Minimum Collection Volume

To achieve a turn around time (TAT) of 7 days, at least 12-15 ml of amniotic fluid must be received.

If a lesser volume of amniotic fluid is sent, the laboratory will attempt to perform the test requested.  The laboratory cannot assure either a result and/or the ability to perform repeat testing and/or additional testing if the minimum volumes are not met.

Shipping/Handling Instructions (Lab Use Only)

Room Temperature. Do NOT spin. Protect from LIGHT. Burnet: Call GENETICS (6-4474) immediately upon arrival.

External Client Shipping and Handling

Store at room temperature  / Use overnight shipping (protect from temperature extremes, no ice) or call the lab for local courier service (contact laboratory prior to drawing specimen to ensure courier area coverage).  Do NOT spin tubes.

Stability (from collection to initiation)

 SEND TO GENETICS to determine viability of specimen; Call the Genetics Lab at 513-636-4474 for pick up or for any questions or concerns about the specimen.

Notes

For twin pregnancies, label tubes with the mother's name and "TWIN A" on one fetal sample and "TWIN B" on the second fetal sample.

The preferred choice for specimen collection is listed above, however, if that tube type/container is not available please call the lab for advice on alternative specimen collection choices.  If the specimen is already collected in a different tube type, send the sample to the lab and we will make every effort to process and result the test.

Collection personnel MUST initial specimen container to confirm sample identity. Label tubes with patient name and date of birth (DOB).

Reflex Testing

Alpha-Fetoprotein (AFP) testing on the amniotic fluid is recommended if specimen is between 13-23.6 wks gestation.  Acetyl Cholinesterase (AChE) testing is ordered if AFP is found to be abnormal or if gestational age is over 22 wks. 

Methodology

Cell culture followed by cytogenetic analysis of fetal metaphase chromosomes.
