From a CRP number to plain context

CRP rises with inflammation but does not say where. LabTestly explains what the value means alongside ESR and WBC when they are present.

⚠️CRP

6.8 mg/L

Above the 3.0 threshold often used for low-grade inflammation. CRP is a general marker — it does not say where the inflammation is, only that some is present. A clinician interprets it with symptoms and other markers.

💚ESR

14 mm/h

Inside range. ESR is another inflammation marker, often reviewed alongside CRP for a fuller picture.

Read more

💚WBC

8.2 K/µL

Right in the middle of normal. White blood cell count is a general index of immune activity, not a specific test for any condition.

⚠️Neutrophils

74%

Just above the 70% upper bound. Mild neutrophil shifts can accompany inflammation; the neutrophil/lymphocyte balance is sometimes informative in clinical context.

FAQ

Questions we hear often

C-reactive protein rises when the body has inflammation. It is a general marker — it does not say WHERE the inflammation is, just that it is present.

High-sensitivity CRP (hs-CRP) uses a more sensitive assay to detect lower levels. It is often used in cardiovascular risk discussions, while standard CRP is more often used for active inflammation.

No. CRP is non-specific — the cause requires clinical assessment. We explain the value and its reference range; the clinician investigates what may be driving it.

Yes. Once you upload more than one report, the dashboard charts CRP and any related markers in your timeline.

No. LabTestly is an educational tool that explains what blood test values mean in plain language. It is not a substitute for professional medical advice, diagnosis, or treatment. We always encourage you to discuss your results with your doctor — every interpretation includes that reminder.

We accept PDFs, JPEGs, PNGs, and WebP files up to 10 MB. This covers printed lab reports, scanned documents, photos taken on your phone, and screenshots from patient portals like MyChart or Quest Diagnostics. If your lab sends a PDF by email, you can upload that directly.

Our AI is trained on medical literature and uses established clinical reference ranges. Interpretations are carefully worded to be educational and accurate. That said, lab values can be affected by many factors — time of day, recent meals, medications — which is why we always encourage a conversation with your doctor for full context.

Privacy First: Your Data, Your Control

  • Files are Temporary: Within seconds of analysis, your original PDF is permanently purged from our servers.
  • Structured Privacy: We only retain the extracted data points (numbers, dates, and markers) to power your charts and chat history.
  • Total Security: All data is encrypted in transit and at rest using industry-leading protocols.
  • Our Zero-Sharing Promise: We never sell your data to insurers, never share it with advertisers, and never use it to train public AI models.

We cover most standard blood panels including Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP), Basic Metabolic Panel (BMP), Lipid Panel, Thyroid function (TSH, T3, T4), Vitamin D and B12, Iron studies, HbA1c, and more. If you upload a panel we don't recognize, we'll tell you.

Absolutely. Every interpretation can be downloaded as a PDF or shared via a secure, expiring link. Many of our users bring their LabTestly summary to appointments as a conversation starter. It's designed to complement — not replace — the doctor-patient relationship.

The free plan includes 1 lab report per month. For most people that is enough if they only test occasionally and just want to understand their results in plain language.

Premium is built for people who want to see the full picture of their health over time. You can upload unlimited lab reports, add older tests, and compare markers as they change.

With Premium you get:

  • Unlimited lab report uploads
  • A full history of all your tests
  • Comparison of markers over time
  • Health timeline — the overall picture of your tests and changes
  • Biomarker map — a visual map of markers across reports
  • PDF export for your doctor
  • A doctor-ready summary that is easy to share at the appointment
  • Priority report processing
  • The ability to upload older tests and see trends
  • More AI-chat questions per report
  • Easy tracking of markers worth keeping an eye on

And much more.
