1.5 mL

Sample cartriges come in 2, 4, or 6 wells loaded with different levels of heparin. Syringe of blood is placed into the machine > blood is distributed into all the wells. The machine lifts the black portion of the well every 5 seconds until a clot is formed

EQC & Plasma QC

* No internal memory * No Software analysis

POC Test:
Sample Size:
Mech of detection:
QC:
Data Storage:
Activator:

HR-ACT, LR-ACT, RACT, PT/PTT, HTC,

0.3 mL / 1 Drop

Infrared light beam through the cartridge detects how long it takes for the black plunger / daisy star to fall through the reaction chamber into the reagent chamber.

EQC & Plasma QC

500 point Internal memory

Celite and CaCl

Bayer/Chiron RapidPoint Coag AKA: TAS
(Throbolytic Assessment System)


POC Test:
Sample Size:
Mech of detection:
QC:
Data Storage:
Activator:

ACT / PT / PTT

0.3 mL / 1 Drop

Credit card style sample cartrige with capillary action that draws the blood sample in through the sample well into the reaction chamber . Paramagnetic Iron Oxide Particles (PIOP) suspended in
liquid sample is influenced by the changing magnetic
forces below the test card
Coagulation prevents the PIOP from moving and the photodetector detects a change in the quantity of light
reflected off the back of the card

EQC & Plasma QC

Internal memory (1000 pts)

Celite

9

Sienco Sonoclot II

POC Test:
Sample Size:
Mech of detection:
QC:
Data Storage:
Activator:

ACT & Clot rate

360 ul

The mechanism is a tubular probe that moves up and down within a blood sample As the sample progresses through various stages of clotting, the electronic circuitry detects increasing resistance.

Plasma & Oil QC

No internal memory

Silica

Heamoscope TEG
* Sensative to motion even from the building*

POC Test:
Sample Size:
Mech of detection:
QC:
Data Storage:
Activator:

(Clotting Time) do not call it an ACT. Heparinase Test Platelet Function Clot Strength Fibrinolysis

A thin wire probe is used to measure, which the clot forms around. The speed and strength of clot formation is measured in various ways, typically by computer.

No internal memory

What is the most significant difference between the TEG and the ROTEM ?

The Sensor shaft rotates on the ROTEM rather than the rotational CUP with the TEG.
