25000 Coenzyme Q10, Reduced and Total, Plasma (Q10)

Coenzyme Q10, Reduced and Total, Plasma (Q10)
Test Code: Q10RTSO
Useful For

Diagnosis of primary CoQ10 deficiencies in some patients who are not supplemented with CoQ10

Diagnosis of coenzyme Q10 (CoQ10) deficiency in mitochondrial disorders

Monitoring CoQ10 status during treatment of various degenerative conditions including Parkinson and Alzheimer disease

This test is not useful for distinguishing primary CoQ10 deficiencies from acquired CoQ10 deficiencies.

This test is appropriate for the diagnosis of secondary coenzyme Q10 (CoQ10) deficiency, and in some patients with primary CoQ10 deficiency who are not supplemented with CoQ10. It is also used to monitor CoQ10 status in patients with mitochondrial cytopathies, patients receiving statin therapy, or during treatment of various degenerative conditions including Parkinson and Alzheimer diseases.

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)
Yes
 8 hours
Heparinized Plasma​ ​Litium-heparin Green Top Tube (GTT) Sodium-heparin Green top Tube (GTT)​ 0.5 mL​ 0.3 mL​
Collection Processing Instructions
Fasting (8 hours)
 

1. Immediately after collection, place specimen on wet ice. Maintain on wet ice and process within 3 hours of collection.

2. Centrifuge, separate plasma from cells, and immediately freeze specimen.

If possible, do not send other tests ordered on same vial of plasma. In doing so, the other tests may have increased turnaround time due to the strict frozen criteria of this assay.

Specimen Stability Information
Specimen Type Temperature Time
​Plasma - Heparinized ​ Frozen (preferred)​ ​14 days
Refrigerated ​ 8 hours​
Rejection Criteria
Gross Hemolysis
Gross Lipemia
Interference

​Coenzyme Q10 (CoQ10) is sensitive to specimen handling and transport temperature. Failure to follow the specimen handling and transportation recommendations may lead to false-positive results.
