The diagnostic process typically involves: Clinical history taking, focusing on symptoms (fatigue, neurological changes, dietary habits) Physical examination for signs of anaemia or neurological impairment Blood tests including full blood count, serum B12, and often folate levels Additional investigations such as intrinsic factor antibodies or parietal cell antibodies if pernicious anaemia is suspected For borderline results, additional tests like holotranscobalamin (active B12) may be considered NICE guidance recommends that treatment should commence based on clinical presentation if neurological symptoms are present, without waiting for laboratory confirmation, as delays can result in irreversible nerve damage

What payers require for Zepbound prior authorization Zepbound PA requirements are typically more stringent: Documented BMI of 30 or greater, or 27 or greater with at least one weight-related comorbidity Evidence of lifestyle intervention including documented participation in diet, exercise, and behavioral modification programs (usually for at least 3 to 6 months) Prior medication trials (some plans require documented failure of other weight management medications before approving tirzepatide) Specialist involvement (some plans require referral to or management by a bariatric medicine specialist, endocrinologist, or obesity medicine physician) Ongoing weight monitoring documentation with specific weight loss targets (typically 5% of baseline weight within 3 to 6 months of starting therapy) Patients researching BMI requirements for GLP-1 medications should understand that these thresholds directly correspond to the prior authorization criteria their provider must document
