What this site is
LabPreparation is an independent information resource about preparing for on-request laboratory tests. The site exists because the hardest part of a lab visit is often the preparation: whether fasting applies, when to collect, which sample a test needs, and what to bring.
How guides are written and reviewed
Every page follows the same structure so you can find an answer quickly: what the test measures, how to prepare, fasting and timing basics, what the collection visit involves, and what to confirm with the lab. Copy is written in plain language and kept evergreen, and pages are condensed from public reference material rather than copied from other sites.
Sources
General test information is compiled from publicly available reference material, including MedlinePlus (medlineplus.gov) and the Centers for Disease Control and Prevention (cdc.gov). Preparation and what-to-bring details reflect the lab's published instructions, paraphrased into our own words. Availability and final requirements always come from the collection lab performing your draw, and the lab's own instructions take priority over anything published here.
What we will not do
We do not fabricate reviews, testimonials, or credentials. We do not publish price claims or diagnostic advice. We do not present our pages as a substitute for a clinician who knows your history.
How to use these guides
Read the prep steps for the test you are considering, bring the checklist to your collection visit, and confirm the details with the lab. When results arrive, review them with a qualified healthcare professional before drawing conclusions.
