Simple Validation

require('bloodtype-validator')( 'a' ) // returns true
require('bloodtype-validator')( 'a', function( error, is_valid ){
  
  // is_valid === true

Strict Validation

In addition to being a valid bloodtype, genotype indicator (+/-) must be included.

require('bloodtype-validator')( 'a', 'strict' ) // returns false
require('bloodtype-validator')( 'a+', 'strict' ) // returns true

require('bloodtype-validator')( 'a', 'strict', function( error, is_valid ){
  
  // is_valid === false
});
require('bloodtype-validator')( 'a+', 'strict', function( error, is_valid ){
  
  // is_valid === true
});
