About GLP-1 Lab Guide

GLP-1GLP-1A gut hormone released after eating that raises insulin, slows the stomach and reduces appetite; the medicines copy it and last much longer. Lab Guide is the laboratory-testing reference of the FormBlends network: one page per blood test that comes up before or during semaglutide or tirzepatide therapy, written from the FDA labels and public reference sources, with two tools that run entirely in your browser.

What the site is

Sixteen test pages (A1cA1cA blood test that reflects average blood sugar over roughly the past three months., fasting glucose, lipid panel, comprehensive metabolic panel, kidney function, liver enzymes, TSH, lipase and amylase, vitamin B12, vitamin D, iron and ferritin, CBC, electrolytes, pregnancy testing, gallbladder imaging, calcitonin), each answering the same five questions: what the test measures, why a prescriber orders it around GLP-1 therapy, what the labels and guidelines actually say about it, what the common reference range is and where that range came from, and how often it is repeated. Around them, four guides: a pre-therapy checklist, a monitoring calendar, a guide to reading a lab report, and a glossary.

Two tools. The lab tracker stores dated results in your browser, draws a trend per test and exports a CSV. The pre-visit checklist turns your therapy stage and conditions into a printable list of labs and questions, each with its source.

Who runs it

The site is written and maintained by the FormBlends editorial team, which also publishes formblends.com. FormBlends operates a GLP-1 weight-loss program that dispenses compounded medicationcompoundedMade by a pharmacy from raw ingredients for a prescription rather than by the brand manufacturer; not FDA approved and not interchangeable with the brand product. through licensed pharmacies. That is a commercial interest, and it is disclosed here, on the medical disclaimer, and wherever a page links to a FormBlends product page. Compounded semaglutide and tirzepatide are not FDA approved and are not interchangeable with the brand products whose labels this site quotes. We quote the brand labels because they are the only FDA-reviewed statements about these molecules, and we treat them as the minimum standard a compounded product should be held to.

How pages are sourced

• Every label statement is quoted or closely paraphrased from the current prescribing information on DailyMed, identified by set id and revision date in the sources list. We read the label text on the date shown, not a summary of it.
• Every reference range is copied from a named public source, almost always a MedlinePlus Medical Encyclopedia page or MedlinePlus Medical Test page, with the access date. Where a guideline defines the categories (KDIGO 2024 for eGFReGFRA calculated measure of how well the kidneys filter blood., the ADA Standards of Care for glucose), the guideline is cited.
• Trial numbers carry a PubMed id and were checked against the abstract.
• Where we could not find a source for a claim, the claim is not on the site. Where guidance is silent (for example, no label sets a routine lab interval), the page says so rather than inventing one.
• Ranges vary by laboratory. Every page says it, because it is true and because the interval on your own report is the one that applies to your sample.

What the site is not

It does not interpret results. It does not tell you whether a value is high, low, safe or dangerous, and the tracker deliberately does not flag values. Interpretation belongs to the clinician who ordered the test and knows the rest of your history. Nothing here is medical advice; read the medical disclaimer.

Editorial rules

No reviews, testimonials, star ratings or named clinicians. No claim of medical review that did not happen. No em dashes. Byline is the FormBlends editorial team. Pages carry an updated date; when a label revision, a guideline update or a MedlinePlus change alters a fact, the page changes and the date moves.

Your data

The tools keep everything in your browser. The tracker uses your browser's local storage so the list survives a reload; nothing is transmitted, there is no account, and clearing site data removes it. Export a CSV if you want a copy. The checklist stores nothing at all. We do not run analytics on the values you enter.

Reporting an error

If a page misquotes a label, cites a range that does not match its source, or states something you cannot verify, email hello@formblends.com with the page URL and the source you checked against. Factual corrections are made as a priority and noted on the page.
