Our Medical Review Team

Two clinicians review the content on insulin-calculator.org. A board-certified endocrinologist covers the human diabetes calculators and guides. A veterinarian covers the pet insulin pages.

What review means here. Our reviewers check the formulas, the guideline alignment and the safety messaging on each page. They do not treat readers through this site. Always confirm dosing decisions with your own doctor, diabetes care team or veterinarian.

Veterinary Reviewer · Veterinarian

Dr. Sánchez Barreras reviews the five pet insulin pages. Canine and feline diabetes sits inside general veterinary practice, and animal insulin differs from human insulin in ways that matter for dosing.

Why two reviewers, not one

A human endocrinologist is not a qualified reviewer for animal insulin dosing, so we split the work by species. The differences are practical, not cosmetic:

  • Concentration differs. Several veterinary insulins are U-40, while human insulin is almost always U-100. Matching the syringe to the concentration prevents a fourfold dosing error.
  • Products differ. Vetsulin (porcine lente) and ProZinc have no direct human equivalent.
  • Outcomes differ. Cats can reach diabetic remission. Humans with Type 1 diabetes cannot.

Dr. Sánchez Barreras reviews the dog insulin calculator, the cat insulin calculator, the Vetsulin dose calculator, the insulin CRI calculator and the pet dosing guide. Dr. Makhija reviews everything else.

What each review covers

  • Formula accuracy. Each calculator implements a published formula. The reviewer confirms the implementation matches the cited source.
  • Guideline alignment. Dose ranges, thresholds and interpretation bands match current ADA Standards of Care or the veterinary sources cited on the page.
  • Safety messaging. Every dosing tool carries warnings, plausibility limits and emergency guidance.
  • Framing. Every result reads as an educational estimate, never as a prescription.

Reviewed pages display a byline naming the reviewer and the review month. Our methodology page documents the full process, including review cadence and how we handle corrections.

Verifying our reviewers

We publish credentials so readers can check them independently. Each profile links to a public professional page. Dr. Makhija's practice and LinkedIn profile appear on her profile page, and Dr. Sánchez Barreras's credentials appear on his.

Found something inaccurate? Contact us. We treat clinical corrections as priority work and escalate them to the relevant reviewer.
