Amniotic fluid IL-6 (IL6) Concentration
| Clinical Significance: | The test is intended for detecting Interleukin -6 levels in amniotic fluid. A high amniotic fluid IL-6 level is a risk indicator for intraamniotic infection. The definitive diagnosis of intraamniotic infection requires amniocentesis and the demonstration of microorganisms within amniotic fluid by culture or 16S ribosomal DNA by PCR. |
| Methodology: | Enzyme immunoassay |
| Test Code: | AFIL6500 |
| Preferred Specimen: | 1.0 mL of Amniotic Fluid |
| Minimum Volume: | 0.5 mL of Amniotic Fluid |
| Transport Container: | Sterile screw cap transport tube provided by ProteoGenix |
| Transport Temperature: | Room temperature (15°C-30°C) if collection and transport
time within 24 hours Frozen (-20°C) if collection and transport time exceeds 24 hours |
| Specimen Stability: | Room temperature (15°C-30°C): 24 hours Refrigerated (2°C-8°C): 1 week Frozen (-20°C): 2 weeks Frozen (-80°C): 18 months |
| Limitations: | Maximum number of freeze-thaw of sample is four (4) |

Specimens received after 12:00 PM on Friday will have results released by 12:00 PM the following Monday. Specimens shipped for rival at the ProteoGenix Clinical Laboratory in Southern California between 5:00 PM Friday and 8:00 AM Monday, should be frozen (-20C) prior to shipment and ship via frozen specimen shipping container. |
| Reference Interval: | ≥ 13 ng/mL Elevated level of IL6 in amniotic fluid.
Consistent with intraamniotic infection. < 13 ng/mL Normal level of IL6 in amniotic fluid |
| Alert Value: | All results equal to or greater than 13 ng/mL are considered
evidence of intraamniotic infection and will be communicated to
the ordering physician or their designee within one hour of
resulting final report. |
