Method Validation (Correlation)
Determine the validity or correlation of recovered values of an analyte with a new method in comparison to the reference method. CLIA Recommendation: Must be done to determine the correlation factor between two methodologies. Method A (New Method): Analyzer: Method B (Comparison Method): Analyzer: Enter up to 30 values below: Method A Method… Continue reading Method Validation (Correlation)
Calibration Verification (Linearity)
Determine the accuracy of calibration throughout the reportable range using different dilutions of an analytical solution. CLIA Recommendation: Must be done every 6 months for non-waived quantitative assays calibrated with less than three levels of calibrators. Number of Levels: 3 4 5 6 Enter Values and Replicates below separated by a comma (e.g. 4,3,6):… Continue reading Calibration Verification (Linearity)
pO2 Barometric Correction for EPOC Blood Gas
Determines the corrected partial oxygen pressure (pO2) from the barometric pressure at current elevation in mmHg for EPOC Blood Gas Analyzers when running aqueous solutions. Formula: Corrected PO2 = PO2 reading + (2mmHg + 6% PO2 reading) x (760mmHg - Barometric pressure)/100mmHg Principle: PO2 readings will decrease by 2mmHg + 6% per 100mmHg barometric pressure… Continue reading pO2 Barometric Correction for EPOC Blood Gas
FIO2 Calculator from LPM (L/Min)
Calculates the Fraction of Inspired Oxygen (FIO2) using the flow rate of Oxygen in L/Min. Formula: FIO2 = Percentage of atmospheric oxygen (20%) + (4 x Flow rate in L/Min) Principle: The percentage calculation of oxygen received by a given flow cannot be precise every time, but relatively accurate estimation can be obtained by relying… Continue reading FIO2 Calculator from LPM (L/Min)

Platelet Estimate (Counter)
Online counter for estimating the patient's platelet count by counting the average number of platelets in 10 fields multiplied by 15,000. Please click here if you would like to use an input form instead. Instructions: Find oil immersion fields with non-overlapping cells. Use the “Platelets” button below to count the number of platelets seen. Then,… Continue reading Platelet Estimate (Counter)
Reticulocyte Count 10 Field Estimate
Determine the patient's reticulocyte count by counting the average number of reticulocytes in 10 oil immersion fields. Please click here if you would like to use our online counter instead. Principle: Microscopically counting the average number of reticulocytes seen in 10 oil immersion fields on a blood film stained with a supravital stain determines the… Continue reading Reticulocyte Count 10 Field Estimate
Sodium Citrate Platelet Correction Calculator
Determine the sample's actual platelet count if it is collected in Sodium Citrate Anticoagulant. Formula: Actual Platelet Count (1000/uL) = Platelet Count (Na Citrate Sample) x 1.1 Principle: Some samples exhibit in vitro platelet clumping if collected in EDTA sample. This will cause a falsely low platelet count. To mitigate this, sample is collected in… Continue reading Sodium Citrate Platelet Correction Calculator
