Is this panel right for me?
Who this panel is built for.
Who this is for
- Athletes and active adults tracking biomarkers that influence training and recovery.
- People in regular structured training reviewing iron status, hormones and inflammation.
- Coaches and athletes wanting objective data alongside subjective performance metrics.
- Anyone in a periodised training block wanting before, mid and after data.
Consider speaking to a clinician first
- Anyone with overtraining symptoms (persistent fatigue, mood changes, injury cluster) without clinician review.
- People with diagnosed cardiac or metabolic conditions who need clinician-directed monitoring.
- Those needing VO2 max or anaerobic threshold testing (these require gas analysis, not blood).
- Children under 18.
This panel reports biomarker data. It does not diagnose any condition. Your results should be reviewed alongside the advice of your GP or another qualified healthcare professional.

FAQs
Common questions.
How long do Sports Performance results take?
Sports Performance results are typically delivered within 3 working days of the laboratory receiving your sample. You receive a plain English PDF report covering recovery, hormone, lipid, iron, vitamin and inflammation markers.
How is the sample collected for Sports Performance?
The Sports Performance panel requires a venous blood draw at a Chxhealth or partner clinic. The phlebotomy fee is included in the price. Choose our Lanchester clinic or one of our 50+ UK partner and pop-up clinics when you book.
Should I avoid training before the test?
Yes. Avoid strenuous exercise for 48 hours before the test. Heavy training can transiently raise muscle markers (CK, AST), liver enzymes, and inflammation markers, which can skew the picture. Light activity is fine.
Who is the Sports Performance panel designed for?
Athletes, regular endurance and strength trainers, and active adults who want to monitor recovery, hormone balance and nutrient status that influence training performance. It pairs well with longitudinal training data.
How often should I retest?
For active athletes, every 3 to 4 months is common, often timed around training blocks. If you are tracking the impact of a specific lifestyle or supplementation change, retest 6 to 12 weeks after the change for a meaningful comparison.
