VariScreen algorithm to rule out esophageal varices needing treatment

1. Single Computation

If you have only one clinical practice computation to perform in clinical practice, use the following form. If you have multiple clinical research computations to perform, see «Multiple Computations».

Step 1: Platelets value (units G/l, accepted range 20-700)

submit reset

Step 2: LSM value (units kPa by VCTE and M probe, accepted range 2-75)

submit reset

Step 3: Sex, INR and Etiology values

Variables Values Units Accepted Range

Sex      none M - F

INR      none   0.6-4

Etiology
           Alcohol        Virus        NAFLD

Interpretation:

If you also calculate a PLER or PLEASE test whose result is discordant with Variscreen algorithm, you should only consider the present Variscreen result (that takes into account discordances).

2. Multiple Computations

Copy your dataset from your Excel file and paste in the yellow area below.

The columns in your Excel file must be in the following order:
Platelets (G/l), LSM (kPa) (for PLER); optional: sex (M/F), INR, etiology (Alcohol, Virus, NAFLD) (for PLEASE and VariScreen).

PLER includes platelets and LSM (by VCTE).

PLEASE additionally includes sex, INR and etiology.

VariScreen is automatically calculated when the variables of PLEASE test are recorded.

VariScreen additionally includes a reliability analysis; therefore, this is the most reliable result
and automatically handles possible discordances between PLER or PLEASE results.

Click on the compute button under your data to retrieve the values of the VariScreen algorithm results.
