General processing of the data

Merging test names

In addition, in certain white blood cells (monocytes, neutrophils, etc.) the displayed unit of measure was volume, rather than percentage. In these cases names were changed to Absolute Monocyte count, Absolute Neutrophil Count, etc. respectively.
Merging units of measurements
The units of measurements were merged to overcome inconsistency with writing styles.

Removal of unreadable records
Records where the values were deemed unreadable were removed. These values were
Overall 1031 records were removed (<0.1%, including all removals listed in this document).

Processing of assessments with Text Values

Merging Text Values
Part I: A variety of text items indicated only the presence or lack of detection. They were merged together according to the following table:
Part II: other items received descriptive measurements rather than numerical ones. They were merged together according to the following table:
'1+ OR 1/4 G/DL'Small
'2+ OR 1/2 G/DL'Moderate
'4+ OR 2 OR MORE'Large
'TRACE OR 1/10 G'Trace
'MANY (21 OR GRE'Large
'Non Hemolyzed Trace'Trace
'Non Hemolyzed Modera'Moderate
Treating '<' and '>'
There were cases in which instead of a numerical value, the assessment results were given as '<' or '>' and a numerical value. In cases where the range represented in the argument was normal, they were replaced with ‘Normal’. If the range wasn’t normal, they were removed.

Some records with test names 'Follicle Stimulating Hormone' and 'Thyroid Stimulating Hormone' were removed due to unit and value incompatibility with other records. They will be added to the dataset in the future after further investigation and necessary cleaning.
Unit conversion for specific Test names
There were cases in which the Unit of measurement was changed for all instances of that combination of Test and Unit of measurement. This could be due to typing error (indicated by the spelling or by a mismatch between the Unit of Measurement and the value), an attempt to merge units with different names but similar meaning, or treating cases of missing Unit of measurements (indicated by an empty cell in the table below)

Alteration of specific values (outlier analysis)
Done if there were two distinct populations separated by a large magnitude, or if a value was undecipherable.
  • For the test 'Creatinine' and unit of measurement 'mmol/L' , 'if x < 10, multiply by 1000 change unit to umol/L)
  • For the test 'Uric Acid' and unit of measurement 'umol/L' , 'if x > 1000, divide by 1000
  • Remove the test 'Urine Ph' if value is <1.5
