Abnormal Blood Tests - What it is

Patients can be referred to a gastroenterologist where the predominant problem is an abnormal blood test result following routine health screening.

By the very nature of these referrals, these patients are either asymptomatic or have very subtle symptoms or signs.

Although some of these issues may have been dealt with in other chapters within this booklet, we will approach these problematic blood test results in a rational and practical manner in this section.Abnormal blood tests Singapore General Hospital

The most commonly referred patients fall into three categories:

  1. Raised tumour markers (Alphafetoprotein [AFP], carcinoembryonic Antigen [CEA], carbohydrate antigen 19-9 [CA19-9])
  2. Anaemia
  3. Abnormal liver function tests
