FixFirst is a blood test analysis tool designed to help individuals interpret their laboratory results by identifying the three most actionable health priorities. It processes uploaded lab reports, whether in PDF format or as a phone photo, and returns a ranked list of markers that are most likely to benefit from intervention. The analysis is personalized based on the user’s age, sex, and lifestyle, and the output includes a clear explanation of why each marker matters along with a corresponding action plan. The tool is especially targeted at people who have been told their labs are within normal ranges but still experience symptoms such as fatigue. The workflow requires the user to upload a blood test report and answer a short set of questions about personal context. FixFirst then applies clinically appropriate thresholds that account for the user’s specific demographics, rather than relying on generic normal ranges. The analysis is completed in approximately 45 seconds. The tool is not a chatbot; it delivers a structured, ranked action plan with medical guidance. The markers shown in sample outputs include LDL cholesterol, vitamin D, and ferritin, with tailored recommendations such as diet adjustments or supplement plans. Technically, the app processes all uploaded data in memory and does not store any information. The extracted data is limited to lab values only; no name, identification number, or contact details are ever processed or retained. The analysis is medically reviewed, with the platform built by Ankit Agarwal and reviewed by Dr. Prahlad Rai Gupta, MBBS, MD (Pulmonary Medicine), who has 31 years of clinical practice. No account or registration is required to use the service. The app is available at fixfirst.health and includes additional features such as a symptom quiz and resources on fatigue related to blood tests.
