Specimen Requirements
| Fasting Required | Specimen Type | Preferred Container/Tube | Acceptable Container/Tube | Specimen Volume | Specimen Minimum Volume (allows for 1 repeat) |
Pediatric Minimum Volume (no repeat) |
|---|---|---|---|---|---|---|
| No | Whole Blood | EDTA Lavender Top Tube (LTT) | EDTA Pink Top Tube (PTT) | 1.0 mL | 0.5 mL | 250 uL |
Collection/Processing Instructions
Submit in the original collection tube. When cyclosporine is IV administered, the specimen should preferably be collected by venipuncture from the opposite arm as specimens from the IV or in-dwelling catheter are often contaminated. If the in-dwelling line must be used, select an alternate lumen if possible and follow the TPN flush and discard volume guidelines.
Draw blood immediately before a scheduled dose to obtain trough level. Therapeutic range applies to trough specimen results.
Specimen can be used for other immunosuppressant drugs testing (i.e. TACRO, SIRO), but DO NOT use this specimen for other blood tests except HGMPA (and then only if absolutely necessary).
Specimen Stability Information
| Specimen Type | Temperature | Time |
|---|---|---|
| Whole Blood | Ambient | 6 hours |
| Refrigerated | 7 days | |
| Frozen | 30 days |
Test Information
This test was developed and its performance characteristics determined by Marshfield Labs. It has not been cleared or approved by the US Food and Drug Administration. This test is used for clinical purposes. It should not be regarded as investigational or for research.
This test is used to determine the level of cyclosporine in blood. Cyclosporine is an immunosuppressant drug that inhibits the body's immune response and is typically administered to prevent the rejection of transplanted organs, e.g. kidney and liver, or tissue, e.g. bone marrow, and may also be used to treat various autoimmune disorders such as Crohn's disease or rheumatoid arthritis. Cyclosporine has a relatively narrow therapeutic range, making drug monitoring necessary to ensure the efficacy of the treatment, and also minimize toxic side effects.
Interpretations
Reference ranges are not available for oncology patients. (Note: ug/L and ng/mL units are equivalent).
Reference Range Information
| Performing Location | Reference Range |
|---|---|
| Marshfield | Therapeutic: 100-400 ng/mL trough levels for transplant patients. Results are reported with a quantitative LC-MS/MS result. The optimal therapeutic range may vary based on the type of transplanted organ, indication for therapy, treatment phase, time of sample collection relative to prior dose, clinical or institutional protocols and/or use with other drugs. Interpretation of results should be in conjunction with the above clinical information and any physical signs of rejection or toxicity. |
