About LabLookup

The specimen collection reference for the clinic floor

LabLookup answers one question quickly and correctly: for this test, at this lab, which tube, how much blood, in what order, under which code, and what gets it rejected. It is built for the clinicians, medical assistants, and phlebotomy staff who collect specimens, so fewer samples come back rejected for the wrong tube or a short draw.

LabLookup is an educational reference for specimen collection, not medical advice. It holds no patient information, does no ordering, and makes no diagnosis. For what a result means for a patient, talk with a qualified clinician.

Why we built it

The hard part of a lab test is rarely knowing what to order. It is collecting it correctly. The right test in the wrong tube, or a tube filled below its minimum, is a specimen the lab rejects, and a rejection means a callback, a redraw, a delay in the result, and a patient stuck twice. The answers exist, but they are scattered across each lab’s directory of service, stated differently by each lab, and easy to get wrong under time pressure.

LabLookup puts those answers in one place, per lab, so the specimen is collected right the first time.

What LabLookup shows

For a test, LabLookup shows each lab’s own requirement side by side, because requirements genuinely differ between labs that run different analyzers:

Collection tube
The stopper color and additive a lab requires, shown as the primary tube plus any alternates the lab lists.
Fill volume
The preferred and the minimum volume the lab states, so a short draw can be judged before it is sent.
Order of draw
Where the tube falls in the CLSI GP41 venipuncture sequence, so additives do not carry between tubes.
Ordering code
The lab’s own order code, so the right test is ordered the first time.
Handling and rejection
Centrifuge, temperature, light and time sensitivity, and the criteria a lab uses to reject a specimen.

Who it is for

Anyone who sits between the order and the draw: nurse practitioners and physicians confirming a collection, medical assistants and phlebotomists at the point of care, and front desk staff fielding a lab’s callback. It works with no login, on a phone, in the seconds before a draw. It is a reference tool, not a record system, and it holds no patient data.

How the data is built, and verified

Every requirement value comes verbatim from a lab’s own published specimen collection manuals and directories of service. LabLookup records what the lab itself states, per lab, and a nurse practitioner reviews it against the source before it is marked verified and shown publicly. Order of draw and tube color follow the CLSI GP41 venipuncture standard. Values still under review are not shown as verified.

The full sourcing and verification process is written up in our methodology.

What LabLookup is not

It is not an electronic health record, a lab ordering system, a results viewer, or a diagnostic tool. It does not interpret results, hold reference ranges, or store any patient information. It is a collection reference, and it is not a substitute for a lab’s official source materials, which remain the final authority for any specimen.
