Real Results. Real Stories.
See how Rezulto helped real people understand their lab results — and in some cases, get the right diagnosis when their doctor missed it.
Iron Deficiency Anemia
Sarah K.
London, United Kingdom
"My doctor told me I was just stressed. Rezulto found I was critically anemic."
Sarah had been exhausted for nearly a year. Her GP ran basic tests and told her the results were fine — just stress. Something still felt wrong, so she uploaded her lab results to Rezulto. Within seconds, the AI flagged her ferritin as critically low and identified a clear pattern of iron deficiency anemia that her doctor had completely overlooked.
Ferritin
warning Criticalapp.reference_range: 20–200 µg/L
Ferritin is your body's iron storage protein. At 6 µg/L — nearly 3× below the minimum — your iron reserves are dangerously depleted. This level causes severe fatigue, brain fog, shortness of breath, and can affect heart function if left untreated.
Hemoglobin
arrow_downward Lowapp.reference_range: 12.0–16.0 g/dL
Hemoglobin carries oxygen through your blood. At 9.2 g/dL you have moderate-to-severe anemia — your organs are receiving significantly less oxygen than they need. This explains the constant exhaustion, dizziness, and difficulty concentrating.
MCV (Mean Corpuscular Volume)
arrow_downward Lowapp.reference_range: 80–100 fL
MCV measures the size of your red blood cells. Small cells at 71 fL, combined with low hemoglobin and critically low ferritin, form a classic triad — microcytic hypochromic anemia — a textbook presentation of iron deficiency that should not have been missed.
What happened next
Sarah took the Rezulto report to a hematologist, who immediately confirmed severe iron deficiency anemia and started IV iron infusion. Within 6 weeks she felt like a different person. Her first doctor had seen the same numbers and said nothing.
Peace of Mind — No Doctor Visit Needed
Michael T.
Texas, United States
"I was about to pay $400 for a doctor visit. Rezulto showed me everything was fine in 30 seconds."
Michael had been feeling slightly off for a few weeks — mild fatigue, occasional headaches. In the US, a doctor visit with bloodwork follow-up easily runs $300–500 out of pocket. Before booking the appointment, he uploaded his recent annual blood panel to Rezulto. The AI went through every marker in detail and confirmed everything was within healthy range, explaining exactly what each value meant and why he had nothing to worry about.
Fasting Glucose
check_circle Normalapp.reference_range: 70–99 mg/dL
Your fasting glucose is 94 mg/dL — comfortably within the healthy range. This means your body is regulating blood sugar well and there are no signs of pre-diabetes or insulin resistance. The mild fatigue you are experiencing is not coming from blood sugar issues.
TSH (Thyroid Stimulating Hormone)
check_circle Normalapp.reference_range: 0.4–4.0 mIU/L
Your TSH is 2.1 mIU/L — right in the middle of the healthy range. Your thyroid is functioning normally and is not the source of your fatigue. Thyroid issues are a common cause of tiredness, but your numbers clearly rule this out.
White Blood Cell Count (WBC)
check_circle Normalapp.reference_range: 4.5–11.0 × 10³/µL
Your white blood cell count is normal at 6.2. This means your immune system is functioning well with no signs of infection, inflammation, or immune suppression. Combined with your other normal markers, your bloodwork paints a picture of good overall health.
What happened next
Michael skipped the appointment and saved $400. He understood his results properly for the first time — not just a number, but what it actually means for his body. He now uploads his annual panel every year as a first step before deciding whether a doctor visit is necessary.
Doctor Recommended — Long Wait Time
Emma L.
Munich, Germany
"My doctor told me to check my results with AI while waiting weeks for my appointment."
Emma's GP had ordered a full blood panel after she complained of persistent fatigue and joint stiffness. But with long specialist wait times in Germany, the follow-up appointment to discuss results was weeks away. Her doctor specifically suggested she use an AI tool to get an initial understanding of her results in the meantime — and flagged that if anything looked urgent, she should call the practice immediately. She uploaded her results to Rezulto that same evening.
CRP (C-Reactive Protein)
warning Highapp.reference_range: < 5.0 mg/L
CRP is your body's primary inflammation marker. At 18.4 mg/L — nearly 4 times the upper limit — there is significant active inflammation somewhere in your body. This level rules out minor causes like a passing cold and points to a systemic inflammatory process. Combined with joint stiffness, this warrants urgent investigation.
ESR (Erythrocyte Sedimentation Rate)
warning Highapp.reference_range: < 20 mm/hr
ESR is a secondary inflammation marker. At 42 mm/hr — more than double the upper limit — this confirms that the elevated CRP is not a one-off reading but reflects ongoing, sustained inflammation. When both CRP and ESR are elevated together with joint symptoms, autoimmune conditions such as rheumatoid arthritis must be ruled out.
Vitamin D (25-OH)
arrow_downward Lowapp.reference_range: 30–100 ng/mL
Vitamin D at 14 ng/mL is significantly deficient. Low Vitamin D is strongly associated with autoimmune conditions and can amplify joint pain and fatigue. In the context of elevated inflammatory markers, correcting Vitamin D deficiency is an important part of the overall treatment plan.
What happened next
Rezulto identified elevated inflammation markers and a Vitamin D pattern consistent with early autoimmune activity. Emma called her GP's practice the next morning and was moved to an urgent slot within 3 days. Her doctor confirmed the findings and referred her to a rheumatologist. The weeks-long wait would have delayed diagnosis significantly.
Severe Vitamin D Deficiency
Priya S.
Mumbai, India
"Three doctors gave me antidepressants. The real problem took Rezulto 30 seconds to find."
Priya had been living with joint pain, constant fatigue, and low mood for over two years. Three different doctors had prescribed antidepressants and pain medication. None had tested her Vitamin D. She uploaded her blood panel to Rezulto, which immediately identified a critically deficient Vitamin D level and explained exactly why it was causing all of her symptoms.
Vitamin D (25-OH)
warning Criticalapp.reference_range: 30–100 ng/mL
Vitamin D at 9 ng/mL is critically deficient — less than a third of the minimum needed. Vitamin D is not just a vitamin; it is a hormone that regulates hundreds of processes in the body. Severe deficiency causes deep bone and joint pain, profound fatigue, depression, muscle weakness, and impaired immune function.
Calcium
arrow_downward Lowapp.reference_range: 2.2–2.6 mmol/L
Vitamin D is essential for calcium absorption. When Vitamin D is critically low, calcium absorption drops — leading to low blood calcium. This contributes to muscle cramps, joint pain, and bone weakness, compounding the symptoms caused by Vitamin D deficiency alone.
Magnesium
arrow_downward Lowapp.reference_range: 0.75–1.0 mmol/L
Magnesium is required to activate Vitamin D in the body. When magnesium is low, supplementing Vitamin D alone is often insufficient. This triad — low Vitamin D, low calcium, low magnesium — explains the severity and persistence of symptoms over two years.
What happened next
A new doctor started Priya on high-dose Vitamin D3 supplementation. Within 8 weeks her joint pain had significantly improved and her mood had normalized completely. Two years of misdiagnosis — solved by a lab result that had been sitting unnoticed in her file.
