Results: What's Next for the Performance Woman

After receiving your performance woman test results, treat the analysis as your first step toward your goals. This is your bridge to insights that let you confidently shape your training.

  • If any results fall outside the reference range, review them with a qualified healthcare provider or sports medicine specialist.
  • Keep in mind that some markers, such as Creatine Kinase or ALT, can rise after intense sessions due to muscle damage rather than an underlying problem.
  • Additionally, use fasting insulin and HbA1c to check how your body manages your current carbohydrate intake.
  • From here, check for nutrient deficiencies. If markers such as Ferritin or Vitamin D are low, discuss targeted supplementation and dietary adjustments with a professional.
  • Similarly, note that high Cortisol or low Testosterone (Testosterone-to-Cortisol ratio) may signal overtraining. Adjust training volume and sleep if this occurs.

Strategic Testing Frequency: Timing Your Insights for Peak Performance

  • Get the most from your analysis, look for trends over time—not isolated results. Pay attention to how your markers shift over months as your training load changes.
  • Baseline Testing: It is ideal to establish a “Bronze” or “Silver” baseline during an off-season or a period of maintenance training to understand your “normal” levels.
  • Standard Monitoring: For most active men, a comprehensive panel every 6 to 12 months is sufficient to track long-term health trends like HbA1c and Lipids.
  • High-Intensity Phases: Elite athletes or those in a “peaking” phase may choose to test every 3 months to monitor acute recovery markers like Creatine Kinase and Free Testosterone.
  • Post-Intervention: If you are correcting a specific deficiency (e.g., Vitamin D or Iron), re-testing the specific marker after 8 to 12 weeks of intervention is recommended to assess progress.

Further Insights

Exercise and Hormones

Hard training is often scapegoated for the hormonal issues women experience, but this is a critical misunderstanding of female physiology. Intense exercise acts as a powerful stimulus—a stressor that can either build you up or break you down.

The Myth of the Exercise-Hormone Link

The belief that vigorous training inherently destroys female hormones is false. Exercise is a strong signal to the body to get stronger. When you train hard, acute bursts of cortisol and growth hormone are released to facilitate adaptation—mobilising energy, repairing muscle, and improving structural strength. Managed correctly, hard training optimises performance.
The damage doesn’t stem from the training intensity; it stems from the mismatch between energy expenditure and inputs. Hard training is essentially high-energy-demand training. If your body isn’t given the specific signals (fuel and rest) required to process that demand, it enters survival mode.
Relative Energy Deficiency in Sport (RED-S) occurs when the hypothalamus senses an ongoing energy shortfall due to excessive work and insufficient recovery. As a result, non-essential systems like reproduction and metabolism downshift. The hormonal disruptions—suppressed estrogen, low thyroid, increased stress hormones—are adaptations to apparent starvation, not exercise itself.

Fuel the Demand, Secure the Adaptation

The difference between elite performance and total hormonal dysfunction is balance. Training is only as good as the fuel you provide. To maintain hormonal health, hard training must be supported by adequate caloric intake—especially carbohydrates, which are the primary hormonal currency for the female brain—and dedicated, structured rest.
To visualise the way these elements combine, consider the accompanying infographic. It makes clear that actual athletic health depends on the alignment of high training stimulus, targeted nutrition, and intentional recovery.

Frequently Asked Questions: Performance Woman Blood Testing

Performance health is multifaceted. Here are common questions about optimising your biology for athletic and daily performance.

General Testing & Timing

  • How often should I test performance markers?

Most active women benefit from testing every 3 to 6 months to monitor the effects of training, diet, and supplements. (Basal Values of Biochemical and Haematological Parameters in Elite Athletes, 2020) After starting a new routine, schedule a follow-up test at 8 weeks to detect early changes. (Skogstad et al., 2016) Your ideal schedule depends on age, training intensity, and health goals. Younger women or beginners may need less frequent testing, while older women, intense trainers, or those with health concerns may require more frequent assessments. (Blood Biomarker Profiling and Monitoring for High-Performance Physiology and Nutrition: Current Perspectives, Limitations and Recommendations, 2019, pp. 1653-1667) Adjust your testing frequency as your goals, health, or training evolve.

  • Should I fast before the blood draw?

 Yes. For the most accurate glucose, cholesterol, and hormone measurements, fast for 8 to 12 hours before your appointment. Hydrate with water to facilitate the blood draw. Eating anything will trigger an insulin spike and temporarily alter your triglyceride and glucose levels, invalidating your metabolic and lipid markers. Also, eating a meal containing iron can artificially inflate your serum iron numbers on the test.

  • What is the best time of day for the test?
The short answer is early morning (between 7:30 AM and 9:00 AM), while fasting.
Because this is a comprehensive list, several biomarkers fluctuate dramatically throughout the day due to your body’s natural circadian rhythms. Standard reference ranges used by labs are almost always based on early morning fasting baselines.
Here is exactly why the morning is your sweet spot.

The Must be Morning

  • Cortisol: Your “stress hormone” follows a strict daily curve. It peaks sharply 30 to 45 minutes after you wake up and drops steadily throughout the day. A cortisol test taken at 2:00 PM is practically useless for evaluating baseline adrenal health unless it is compared with a morning sample.
  • Testosterone: In both men and women, testosterone levels are at their absolute highest in the early morning and can drop by up to 20–30% later in the day.
  • TSH (Thyroid Stimulating Hormone): TSH has a circadian rhythm that peaks overnight and drops to its lowest point by late afternoon. To catch your true baseline and avoid missing a subtle underactive thyroid (hypothyroidism), a morning test is essential.
  • Iron Panel & Ferritin: Serum iron levels can fluctuate wildly by 30–50% over the course of a single day, usually peaking in the morning and dropping by the evening.
  • Medication/Supplement check: If you take biotin (common in hair, skin, and nail vitamins), stop it 48 to 72 hours beforehand. Biotin interferes with lab assays, causing falsely high thyroid hormones (FT3/FT4) and falsely low TSH. If you take thyroid medication, hold your dose until after the blood test.

Markers That Stay Stable

The rest of your panel—like HbA1c (which reflects a 3-month average of blood sugar), Vitamin D, Vitamin B12, Thyroid Antibodies, hs-CRP, and your Full Blood Count—are relatively stable and do not depend on the time you show up. However, they easily fit into the morning schedule required by the rest.
 

⚠️ A Crucial Note for the “Female Hormones” (Oestradiol, LH, FSH, Progesterone):

While the time of day matters for the reasons above, the day of your menstrual cycle is critical for these markers.
  • Oestradiol, LH, and FSH are typically tested during Days 2 to 5 of your period (the follicular phase) to establish a baseline.
  • Progesterone is usually tested on Day 21 of a standard 28-day cycle (or 7 days after ovulation) to confirm if ovulation actually occurred.
If you take them all on the same day, you will get a snapshot of that specific moment, but you’ll want to interpret the female hormones strictly based on exactly where you were in your cycle that morning.
Checklist for the Morning of Your Test:

  • What distinguishes “Normal” from “Optimal”?

“Normal” ranges show what’s typical in the population, including inactive or unhealthy people. “Optimal” ranges are narrower, reflecting the levels at which high performers excel. Athlete studies determine these values, prioritising peak performance over minimum health. (Martínez et al., 2022) Our reports show these zones so you can aim beyond simply avoiding illness.

If your results fall between the “normal” and “optimal” ranges, use this as feedback for improvement. It means your values are healthy, but there may still be room to enhance your training, recovery, nutrition, or supplement strategy to reach peak performance. Consider discussing targeted adjustments with a coach or nutritionist and monitor your next results to track progress.

  • Do enzymes (ALT/AST) rise after workouts?

Intense weightlifting can briefly increase liver enzymes due to muscle breakdown, not liver damage. (Kim & Wu, 2020) For accurate results, avoid strenuous exercise for 24 to 48 hours before testing.

Performance Specifics

  • Will this test show if my supplements are effective?

Yes, accuracy varies by marker because each blood test measures different forms and locations of nutrients in your body. Some markers are tightly regulated in the blood, while others reflect longer-term stores or are affected by inflammation or illness. Biological differences mean blood tests can track trends over time, but not all results reflect your true overall status equally. Allow enough time for levels to shift before retesting.

Breakdown by Marker/Supplement

  • Vitamin D (25-hydroxy): Highly reliable. It directly reflects your circulating levels. (Evaluation, Treatment, and Prevention of Vitamin D Deficiency).
  • Ferritin (Iron Stores): Reliable, with a catch. It tracks long-term iron storage, but can show a falsely high reading if you are sick or have inflammation. To check whether inflammation is affecting your ferritin, watch for signs such as fatigue, fever, or body aches, or ask your healthcare provider to run a C-reactive protein (CRP) test.
    • Tip: Wait 3 months before retesting to see substantial progress.
  • Magnesium (Serum): Least reliable. Only 1% of your body’s magnesium is in the blood. Levels may appear normal even if you are depleted elsewhere. If you have symptoms like muscle cramps, fatigue, or an irregular heartbeat but your serum magnesium is normal, consider speaking with a medical provider for further evaluation and advice.
    • Tip: Ask for an RBC Magnesium test for a more precise reflection of your cellular status.

Tip: When Selecting Supplements.

Look for brands that are third-party tested for purity and ingredient accuracy. Choose products that carry certifications by organisations such as NSF Certified for Sport, Informed Choice, or USP, or have a clear batch testing policy published on the company’s website. Avoid supplements with proprietary blends or unclear labelling. Switching to reputable, third-party-tested supplements or modifying your dosage may help. Ask your healthcare provider about additional tests or dietary adjustments if necessary.

  • Can blood tests detect overtraining syndrome?

Yes. We check the Cortisol-to-Testosterone ratio and the Creatinine Kinase (CK) level. High Cortisol and low Testosterone suggest poor recovery from training.

  • What if my results are “Red” or out of range?

Stay calm. A “Red” result is one data point, not a diagnosis. Retest in 1 to 2 weeks, especially if you recently had intense exercise, illness, or lifestyle changes before the blood draw. Evaluate your recent sleep, hydration, stress, and nutrition. Minor adjustments can often correct results. For example, aim for 7 to 9 hours of quality sleep per night, increase your daily water intake, reduce alcohol consumption, or add more fruits, vegetables, and lean protein to your meals. Review your supplement or medication usage and try to manage stress through relaxation techniques or lighter training weeks. If you suspect overtraining, add more rest days or try active recovery sessions. If levels remain out of range after retesting, or if you have symptoms, share your report with your GP or sports doctor for next steps. Small lifestyle changes can normalise these values.
