You've asked your pediatrician. They said "it's just puberty." Maybe it is — but you deserve more than a guess.
Low iron is the most common missed cause of childhood fatigue — and it won't show up on a standard blood count until it's severe. The right test catches it early, when a simple supplement can fix it.
Is it a late bloom or something worth investigating? Growth hormone markers and tracking over time give you a real answer — no 6-month wait for a specialist.
Young athletes deplete iron faster, recover slower, and often don't eat enough to keep up with training. The right blood work shows exactly what's running low before the next stress fracture.
Adult testing platforms don't work for children. The reference ranges are wrong, the interpretation misses how puberty changes everything, and most can't even order labs for minors. We built this for ages 10–18.
What you catch now is what you can actually fix.
Adolescence is the one window where small changes make a lasting difference — better sleep, the right supplement, catching a thyroid issue early. After they're grown, you can only manage. Right now, you can still shape the trajectory.
Your pediatrician checks if something is wrong. They rarely have time to check if everything is right. Here's what falls through the cracks.
Iron stores can run on empty long before a standard blood count catches it. Your child's labs say "fine" — but they can't focus, can't keep up, and nobody knows why.
A borderline thyroid result gets filed as normal. But for a growing child, "borderline" can mean brain fog, weight gain, and exhaustion — and without context, no one looks twice.
Insulin resistance shows up years before blood sugar goes abnormal. Most children never get tested. By the time it's obvious, you've lost the window where diet and exercise alone can fix it.
Every child gets a comprehensive blood panel. Based on their health profile, we add targeted testing for growth, athletics, or mood. You're testing what matters for your child — not running the same panel on everyone.
Iron, thyroid, metabolic health, vitamin D, lipids, liver function, and more — everything a thorough pediatrician would order if they had 60 minutes instead of 15. One draw, twice a year.
A health questionnaire at sign-up identifies what your child needs — growth hormone markers, athletic recovery panels, or fatigue workup. No two reports look the same.
The same iron level means something completely different in a 14-year-old swimmer than in a 40-year-old adult. We factor in age, sex, growth rate, activity level, and family history — nothing gets filed as "normal" without the full picture.
A pediatrician in our network reviews and signs off on every result before you see it — not an algorithm alone. A physician who understands what these numbers mean for a growing child.
What to supplement, what to change, and when to see a specialist — clear recommendations you can act on, not a PDF of numbers with no context.
Retest every 6 months and see how your child's health is trending. Spot improvements, flag new issues early, and build a health record that follows them into adulthood.
When you sign up, we ask about your child's growth, activity, sleep, and mood. Based on their profile, we add the panels that matter most for them.
Growth hormone markers that show whether your child is tracking normally — no months-long wait for a specialist.
Hormone levels that clarify whether puberty is starting too early, too late, or progressing normally.
Spot iron depletion, overtraining, and under-fueling before they lead to injuries or burnout.
Nutritional deficiencies that mimic depression and chronic fatigue — fixable once you find them.
"Normal" doesn't mean the same thing at 14 as it does at 40.
Most lab results get compared against adult ranges. But a growing child isn't a small adult — an iron level that's fine for you might be why your daughter can't get through practice. We interpret every result for where your child actually is in development.
Answer questions about their growth, activity, sleep, and mood. We use this to personalize which tests they get.
Visit a lab near you (2,000+ locations). One or two tubes, around 10 minutes. We send numbing cream in the welcome kit.
We read every result in context — your child's age, stage, and health profile. A pediatrician reviews everything before you see it.
Clear results, specific recommendations, and what to do next. Retest in 6 months to track what's changed.
Everything included — blood work, personalized testing, pediatrician review, action plan, and a dashboard to track it all. HSA/FSA eligible.
