'thickness in blood perhaps?' is the definition.
I can't tell whether this defines the answer.

'beginnings of virulent intestinal cytosis possibly' is the wordplay.
'beginnings of' indicates taking the first letters.
'possibly' is an anagram indicator.
The initial letters of 'virulent intestinal' is 'vi'.
'cytosis' anagrammed gives 'scosity'.
'vi'+'scosity'='VISCOSITY'

'leads to' acts as a link.
