Fluid Lipids
Urine monovette or white topped universal (no additives)
| Test | Fluid Lipids |
|---|---|
| Common Abbreviations | FLCHO, FLTRIG |
| Profile | Includes cholesterol and triglyceride |
| Tube type | Urine monovette or white topped universal (no additives) |
| Clinical Indication | Fluid lipid measurement is used to identify the presence of fluid accumulation due to chylothorax. |
| Specimen Type | Fluid |
| Sample type | Fluid |
| Minimum Volume | 1mL |
| Special Precautions | Please visually inspect samples before sending for analysis and indicate the site of collection. Samples which are very turbid or thick may be rejected as there is a risk of damage to laboratory equipment |
| Stability | No specific data available for fluids. Cholesterol and triglycerides are stable in serum for 2 days at 2-8°C and 7 days at 15-25°C |
| Turnaround Time | Inpatient: 6 hours Outpatient/ GP: 24 hours |
| Laboratory | York and Scarborough |
| Reference Interval | Chylothorax is likely if there is visible presence of chylomicrons after centrifugation of the sample and / or if the fluid triglyceride level is >1.24mmol/L. Fluid triglycerides <0.56mmol/L usually excludes chylothorax. Fluid cholesterol >5.18mmol/L is diagnostic of pseudochylothorax |
| Limitations | Fluid composition tends to be very variable, and the exact mixture of components in a fluid sample can have unpredictable effects on measurement of any one analyte. Our laboratory methods are NOT CE-marked or validated for analysis of fluids, and no specific quality control materials are available. ALL results must be interpreted with caution. |
