Special Instructions

Call the lab to schedule or order laboratory performed testing at the bedside

Turnaround Time

Performed daily; results are available immediately.

Use

Monitor a patient's anticoagulation state during high dose heparin administration.

Specimen Type

Whole Blood

Collection Containers

See Collection Instructions, Plain syringe
ACT cartridge available from laboratory

Collection Instructions

Venipuncture Collection: Use two plain syringes to minimize thromboplastin contamination. Collect 2 mL into the first syringe and discard, into the second syringe collect 0.2 mL to be used for testing. Do not use heparinized syringes. Catheter Collection: Flush anticoagulated catheter with 5 mL of saline. Collect 5-10 mL waste and discard, into a second plain syringe collect 0.2 mL to be used for testing.

Collection Volume

0.2 mL

Minimum Collection Volume

0.04 mL

Unacceptable Conditions

Extraneous heparin present in the sample; heparinized syringes; samples not collected immediately prior to testing.

Stability (from collection to initiation)

Test immediately. For questions, contact the laboratory point of care team at your facility.

Containers

Plain Syringe

Alternate Containers

ACT Cartridge, available from laboratory

Reference Interval

 74-150 seconds

Therapeutic Range

Dependent on clinical procedure.


Sheath Pull Guidelines:

  • If value is < 180 seconds, no further testing is required. The laboratory places orders for follow-up testing if the result is >180 seconds.
  • If value is greater than 180, repeat ACT in 60 minutes.
  • If two consecutive results show no decline in the ACT, a PTT or Heparin 10a level is recommended. Sheath may be removed when PTT is less than 40 seconds or the Heparin 10a level is less than 0.10 IU/mL. Occasionally patients may have baseline ACT values greater than 180 seconds. If these are two consecutive tests that show no decrease in ACT results, a PTT or AXA should be ordered.


Testing Guidelines for PRISMA Patients:

  • 160-180 seconds for normal heparin.
  • 140-150 for minimal heparin

 

Contraindications

Testing should be performed immediately. If there is a delay in testing or a repeat measurement is needed, a fresh sample must be collected.
