1According to CLSI standards, what is the correct order of draw when collecting a light blue (sodium citrate) tube and a gold (SST) tube in the same venipuncture?

A.Gold tube first, then light blue tube

B.Light blue tube first, then gold tube

C.Either order is acceptable because both tubes contain additives

D.A discard tube must be drawn before either tube

Explanation: CLSI guidelines require the light blue sodium citrate tube to be drawn before the gold SST tube. The clot activator in the SST tube can contaminate the citrate tube and falsely shorten coagulation test results (PT, PTT, D-dimer). However, a discard tube is only needed when using a winged (butterfly) needle set to clear the air space.

2A phlebotomist is collecting multiple tubes using a butterfly needle. Which tube should be drawn FIRST according to CLSI order of draw guidelines?

A.Light blue (sodium citrate) tube

B.Discard tube (red or clear)

C.Gold SST tube

D.Lavender EDTA tube

Explanation: When using a winged blood collection (butterfly) set, a discard tube must be drawn first to fill the dead space (air in the tubing) before drawing the sodium citrate tube. Failure to use a discard tube will underfill the citrate tube, skewing the 9:1 blood-to-citrate ratio and producing falsely prolonged coagulation results.

3What is the correct CLSI order of draw for the following four tubes: lavender, light blue, gold SST, and blood culture bottle?

A.Light blue → Blood culture → Gold SST → Lavender

B.Blood culture → Light blue → Gold SST → Lavender

C.Gold SST → Light blue → Blood culture → Lavender

D.Lavender → Blood culture → Light blue → Gold SST

Explanation: CLSI order of draw: (1) Blood cultures first to minimize contamination; (2) Light blue sodium citrate for coagulation tests; (3) Serum tubes such as gold SST; (4) EDTA tubes such as lavender last. This sequence prevents additive carryover that would interfere with test results.

4Which additive is found in the light blue-top tube and what is its primary function in coagulation testing?

A.EDTA — binds calcium to prevent clotting

B.Sodium citrate — chelates calcium to prevent clotting and preserves clotting factors

C.Lithium heparin — inhibits thrombin activity

D.Sodium fluoride — inhibits glycolysis to preserve analyte stability

Explanation: Light blue-top tubes contain 3.2% sodium citrate, which chelates (binds) ionized calcium, an essential cofactor for the coagulation cascade. This reversibly prevents clotting and preserves the coagulation factors needed for PT/INR, aPTT, D-dimer, fibrinogen, and factor assay testing. The required blood-to-citrate ratio is 9:1.

5A lavender-top tube must be filled to the correct volume line. What is the primary additive and what test is it most commonly used for?

A.Sodium heparin — electrolyte panels

B.K₂ EDTA — complete blood count (CBC)

C.Sodium citrate — prothrombin time (PT/INR)

D.Sodium fluoride — fasting glucose

Explanation: Lavender (purple) top tubes contain EDTA (ethylenediaminetetraacetic acid), most commonly as the dipotassium (K₂) salt. EDTA chelates calcium and magnesium, preventing clotting while preserving cell morphology. It is the preferred anticoagulant for CBC, differential, hemoglobin A1c, reticulocyte count, and platelet count testing.

6The gray-top tube contains which two additives, and what is its primary clinical use?

A.Sodium citrate and heparin — coagulation panels

B.EDTA and gel separator — blood banking

C.Sodium fluoride and potassium oxalate — glucose and lactate testing

D.Clot activator and gel separator — serum chemistry

Explanation: Gray-top tubes contain sodium fluoride (a glycolytic inhibitor that prevents cells from metabolizing glucose) and potassium oxalate (an anticoagulant that chelates calcium). This combination preserves glucose levels in specimens and is used for fasting glucose, glucose tolerance tests (GTT), and lactate measurements where delayed processing would otherwise lower glucose concentrations.

7A patient is ordered a blood culture. Which action by the phlebotomist is MOST important before collecting the specimen?

A.Apply tourniquet for 3 minutes before drawing

B.Perform a 30–60 second antiseptic scrub of the venipuncture site with chlorhexidine or iodine

C.Draw the blood culture after all other tubes

D.Use a lavender EDTA tube as a discard tube first

Explanation: Blood cultures are drawn first to minimize contamination. A rigorous skin antisepsis (30–60 second friction scrub with 70% isopropyl alcohol followed by chlorhexidine gluconate or povidone-iodine, allowed to fully dry) is the single most critical step to prevent false-positive cultures caused by skin flora contamination. Tourniquet time should not exceed 60 seconds total.

8Which tube is preferred for blood bank/transfusion medicine testing (ABO/Rh typing and crossmatch)?

A.Gold SST tube

B.Light green PST tube

C.Pink EDTA tube

D.Royal blue EDTA tube

Explanation: Pink-top tubes contain K₂ EDTA and are specifically designated for blood bank/transfusion medicine specimens including ABO/Rh typing, antibody screening, and compatibility crossmatching. Facilities require bedside verification with two patient identifiers and handwritten labeling at the bedside before collection due to the critical safety implications of blood bank testing errors.

9For which test is a royal blue-top tube most commonly used?

A.PT/INR

B.Trace elements such as lead, mercury, arsenic, and zinc

C.Fasting glucose

D.Complete blood count

Explanation: Royal blue-top tubes are made of low-trace-element plastic to prevent contamination of samples tested for toxic or nutritional metals such as lead, mercury, arsenic, copper, zinc, selenium, and aluminum. They may contain EDTA, heparin, or no additive depending on the specific test ordered, and must be collected in a metal-free environment.

10A black-top tube is ordered. What additive does it contain and for which test is it used?

A.Sodium fluoride — lactate

B.Sodium citrate (4:1 ratio) — erythrocyte sedimentation rate (ESR)

C.EDTA — hemoglobin A1c

D.Heparin — ammonia levels

Explanation: Black-top tubes contain sodium citrate at a 4:1 blood-to-citrate ratio (compared to 9:1 in light blue tubes). They are specifically designed for the Westergren erythrocyte sedimentation rate (ESR) test. The tube must be filled to the correct level to maintain this ratio; underfilling causes a falsely elevated ESR.

About the AMCA PTC Exam

The AMCA Phlebotomy Technician Certification (PTC) validates competency in phlebotomy and specimen collection for allied health careers. The 100-question exam covers six domains: Collection of Blood and Non-Blood Specimens (29%), Professionalism and Regulatory Compliance (18%), Patient Identification, Assessment, and Site Preparation (17%), Infection Control and Safety (16%), Equipment Selection and Maintenance (10%), and Specimen Processing and Transportation (10%). Content includes CLSI order of draw, tube additives, OSHA bloodborne pathogen standards, patient identification protocols, venipuncture and capillary techniques, and specimen handling.
