🧴 Preparation, Vials & Supply
Dilute insulin for tiny doses and plan vials, days supply and refills.
Insulin Dilution Calculator
Mix insulin and diluent to a target concentration like U-10 or U-50.
Insulin Vial Calculator
How long a vial lasts and how many vials you need, with the 28-day rule.
Insulin Refill & Days Supply
Days supply and refill-by date from your dose and units dispensed.
What "specialty & clinical" covers
This category gathers the tools that go beyond everyday dosing — for complex meals, specific conditions, hospital and emergency care, and veterinary use. Each is built on cited clinical sources and is meant as an educational reference rather than a treatment protocol.
Complex meals & CGM
The Warsaw Method doses fat and protein as fat-protein units, the CGM trend-arrow tool factors glucose direction into a correction, and the food insulin index and glycemic index show how foods drive insulin and glucose.
Hospital, steroids & emergencies
Glucocorticoids — including antenatal betamethasone — raise insulin needs, while DKA management uses a weight-based insulin drip, severity grading from the anion gap, and the glucose infusion rate in neonatal and critical care. These are clinician-and-student references for in-hospital settings.
Veterinary & diagnostic
The cat and insulin CRI tools support diabetic pets (often U-40 insulin, vet-supervised), and the insulin-to-C-peptide ratio helps distinguish the body's own insulin from injected insulin in a hypoglycemia workup.
Frequently Asked Questions
What is fat-protein (Warsaw Method) insulin dosing?
The Warsaw Method doses insulin for the fat and protein in a meal, not just carbohydrate. Fat and protein are converted into fat-protein units (FPU) and given as an extended bolus to match the slow, late glucose rise from foods like pizza. It's an advanced technique used mainly on insulin pumps.
Are the DKA calculators for home use?
No. Diabetic ketoacidosis is a medical emergency managed in hospital with IV fluids, electrolyte monitoring and a protocol. The DKA insulin drip and assessment tools are educational references for clinicians and students. If you suspect DKA, seek emergency care immediately.
How do steroids affect insulin needs?
Glucocorticoids such as prednisone, dexamethasone and antenatal betamethasone cause insulin resistance and raise blood glucose, so insulin requirements increase while the steroid is active and are reduced as it is tapered. These tools estimate the typical pattern under clinical supervision.
Can these calculators be used for pets?
Some are veterinary references — the cat insulin and insulin CRI calculators estimate feline and canine dosing. They are educational only; diabetic pets must be dosed by a veterinarian using a glucose curve, and many pet insulins are U-40 rather than U-100.
What is the difference between the food insulin index and glycemic index?
The glycemic index rates how a food's carbohydrate raises blood glucose. The food insulin index measures the actual insulin response, so it also captures protein and some fat — which is why high-protein, low-carb foods can still drive insulin.
Who are the specialty and clinical tools for?
They serve advanced users, caregivers, students and clinicians who need condition-specific references — fat-protein dosing, CGM corrections, steroids, DKA, glucose infusion and veterinary dosing. Every tool is educational, not a prescription or a protocol.
