Annual blood tests recommended for seniors (60+)

Test	Why it matters after 60
CBC (Full Blood Count)	Anaemia common in elderly: often from iron, B12 or chronic disease; leukaemia risk rises with age
TSH (Thyroid)	Thyroid underactivity affects roughly 1 in 8 to 1 in 5 women over 60 depending on the population and whether subclinical cases are counted: causes fatigue, weight gain, cognitive slowing
Fasting glucose / HbA1c	Type 2 diabetes doubles in prevalence after 60; often asymptomatic initially
Lipid profile	Cardiovascular risk peaks after 60; statin therapy benefit greatest in high-risk seniors
eGFR / creatinine	Kidney function naturally declines 1% per year after 40: medications need dose adjustment in CKD
Vitamin B12	Absorption decreases with age and atrophic gastritis; neurological damage from deficiency is insidious
Vitamin D	Deficiency affects 70% of seniors; bone fracture risk rises dramatically with low Vitamin D
Calcium	Hypercalcaemia from hyperparathyroidism or malignancy: more common after 60
PSA (men over 50)	Prostate cancer screening: discuss risks and benefits with doctor
Urine ACR	Early kidney damage: often from long-standing hypertension or diabetes

Why seniors need different reference ranges

Age affects normal values

Some blood test reference ranges differ in older adults. Creatinine may appear falsely reassuring: muscle mass declines with age, producing less creatinine even when kidney function is poor. eGFR is more accurate than creatinine alone. Haemoglobin naturally declines slightly with age, but significant anaemia is never "normal ageing" and always needs investigation. TSH reference ranges shift slightly upwards with age, some experts suggest a TSH up to 6.0 mIU/L may be acceptable in those over 80.

Signs that should trigger urgent blood tests in seniors

Unexplained weight loss: rule out cancer, thyroid disease, depression
New confusion or memory decline: check B12, thyroid, glucose, calcium
Fatigue worse than usual: anaemia, thyroid, kidney disease, diabetes
Frequent falls: check Vitamin D, calcium, B12 for neurological causes
New joint pain: uric acid (gout), CRP/ESR (inflammatory arthritis)

Why health test targets change with age

Many laboratory reference ranges and clinical targets that apply to adults in their 40s require modification in people over 75. This is clinically important: treating to the same targets regardless of age can cause harm. Key age-related adjustments:

Blood pressure: NICE guidance (NG136) recommends a systolic blood pressure target of 150 mmHg for adults over 80, rather than the 140 mmHg target used for younger adults. Aggressive blood pressure lowering in frail older adults increases falls risk. Postural hypotension – a drop of 20 mmHg systolic on standing – is common and should be actively looked for by measuring blood pressure lying and standing.
Kidney function (eGFR): GFR naturally declines with age – approximately 1 mL/min/1.73m² per year after the age of 40. An eGFR of 55 in an 80-year-old may represent normal ageing, whereas the same eGFR in a 40-year-old indicates CKD stage 3a. Clinical judgment is required.
Haemoglobin: A haemoglobin of 115–120 g/L is often accepted in frail elderly patients without extensive investigation – particularly if asymptomatic – as aggressive investigation and treatment carries procedural risk. However, anaemia is never "normal" and its cause should always be sought.
HbA1c (diabetes): For older adults with diabetes, especially those with frailty or limited life expectancy, NICE recommends a relaxed HbA1c target of 53–58 mmol/mol (7–7.5%) rather than the 48 mmol/mol target used in younger adults. Tight glucose control in frail elderly patients increases hypoglycaemia risk without proven long-term benefit in this population.

Tests for frailty and falls risk

Clinical frailty – a state of increased vulnerability to adverse outcomes from stressors – is increasingly assessed formally using validated tools:

Clinical Frailty Scale (CFS): A 9-point scale from Very Fit (1) to Terminally Ill (9), based on clinical judgement of activity levels and dependence. Scores of 5 and above indicate at least moderate frailty.
Gait speed / Timed Up and Go (TUG) test: A gait speed below 0.8 m/s or a TUG time above 12 seconds is a reliable predictor of falls, hospitalisation, and mortality in older adults.
Grip strength (dynamometry): Reduced grip strength is one of the key diagnostic criteria for sarcopenia (age-related muscle loss) and independently predicts cardiovascular mortality. The European Working Group on Sarcopenia defines low grip strength as below 27 kg in men and below 16 kg in women.
Bone density (DXA): Recommended for all women over 65 and all men over 70, or earlier if significant risk factors (prior fragility fracture, steroid use, early menopause, low BMI) are present. A T-score below −2.5 at the hip or spine meets the WHO definition of osteoporosis.
