Test Parameters & Specifications
Sample Stability
- Hemolyzed samples
- Samples in incorrect containers or with insufficient volume
- Samples not shipped refrigerated or frozen
Understanding Your Results
Responsive Genotype
Likely to benefit from beta-2 agonist therapy, with improved symptom control
Non-responsive Genotype
May have reduced response to beta-2 agonists; alternative treatments may be considered
Heterozygous Variant
Variable response; monitoring and dosage adjustments may be needed
If you experience persistent respiratory symptoms, have been diagnosed with asthma or COPD, or are not responding well to beta-2 agonist medications, consult your healthcare provider to discuss ADRB2 genotyping and personalized treatment options.
Limitations
- ⚠Does not diagnose respiratory conditions; only assesses genetic predisposition to drug response
- ⚠Results should be interpreted in conjunction with clinical symptoms and other diagnostic tests
- ⚠Limited to known ADRB2 gene variants; rare mutations may not be detected
- ⚠Effectiveness may vary based on ethnic and genetic background
Risks & Considerations
- ●Minor bruising or pain at the blood draw site
- ●Rare risk of infection or fainting during venipuncture
Interfering Factors
- ●Recent blood transfusions may affect DNA analysis
- ●Hemolyzed or improperly stored samples can impact test accuracy
- ●Certain medications may interfere with genetic expression, though not directly with genotyping
