What the standards say

Rule / FactDetail
Order of draw (start)Blood culture → light-blue (citrate) → red/gold (serum) → green (heparin) → lavender (EDTA) → grey (fluoride) (CLSI GP41 order of draw)
Tube colour = additiveLavender=EDTA (hematology/CBC) · Light-blue=sodium citrate (coagulation) · Green=heparin (plasma chemistry) · Gold=SST (serum chemistry) · Grey=fluoride (glucose) (standard tube-colour practice)
Patient IDTwo unique identifiers (full name + date of birth) matched to the requisition; never identify by room number (standard patient-safety practice)
Specimen rejectionMislabeled, hemolyzed, clotted or under-filled specimens must be rejected and redrawn (standard specimen-quality policy)

Why practice with numbers? Phlebotomy exams are rule-heavy: the order of draw, tube stopper colours and their additives, patient-identification steps and OSHA safety rules come up again and again. Memorising the key facts — blood culture first, lavender=EDTA, light-blue=citrate, two patient identifiers, needle at 15–30 degrees — covers a large share of the scored questions. This page's questions are built around those rules so the facts stick.

How to use this page: answer each question, note whether you got it right, and read the explanation either way. The explanations are where most of the learning happens — they connect each question to the underlying standard so you can answer a differently-worded version of the same idea on exam day.

One practical tip: drill the order of draw until you can recite it without thinking — it is the single most-tested routine fact in phlebotomy exams, and getting it wrong in practice means contaminated samples in the lab. Aim to score above 80% on three consecutive practice sets before booking the real exam.

Finally, treat this page as a warm-up rather than a substitute for the official material. The questions here mirror the exam's style and topics, but the credentialing organization's official outline and your program's materials remain the authoritative sources for every rule tested.

Common questions

How many questions are on the NHA CPT exam?

The NHA Certified Phlebotomy Technician exam has 100 scored questions plus 20 pretest (unscored) items. Passing is based on the 100 scored questions (NHA published exam information).

What is the order of draw?

Blood culture → light-blue (citrate) → red/gold (serum) → green (heparin) → lavender (EDTA) → grey (fluoride). It prevents additive carryover between tubes (CLSI GP41).

Do practice tests here match the real exam?

They mirror the topics and style of the real exam, written from public phlebotomy standards — original questions, never copied from other quiz sites.

Can I retake the test?
