Test ID: LBCR    
Lamellar Body Count Reflex, Amniotic Fluid

Specimen Type Describes the specimen type needed for testing

Amniotic Fld

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Collection Container/Tube: Amniotic fluid container

Submission Container/Tube: Plastic vial

Specimen Volume: 10 mL

Collection Instructions: Do not centrifuge.

Additional Information: Centrifuging the specimen may cause erroneous results.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

10 mL; In the advent of indeterminate results this test will be forwarded for additional testing involving chromatographic determination of the L/S ratio. The 10 mL of specimen should be sent as an assurance this option can be exercised.

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected


Visible hemolysis, reject







Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
