SampleVenous blood (serum, whole blood for blood count and erythrocyte sedimentation rate)

PreparationIn the morning, after fasting for 8–12 hours; not during an infection

What this package is for

Eight tests to guide the initial investigation of joint pain: whether inflammation is present (C-reactive protein (CRP), erythrocyte sedimentation rate (OB), full blood count with differential), whether it has rheumatoid features (rheumatoid factor (RF)), whether gout is more likely (uric acid), how the kidneys and liver are functioning before treatment (creatinine, alanine aminotransferase (ALAT)), and whether serum proteins show evidence of chronic inflammation or autoimmune disease (serum protein electrophoresis: albumin and globulin fractions). The package does not diagnose a disease, but helps a doctor distinguish inflammatory arthritis from osteoarthritis and overuse, and decide whether a rheumatologist is needed.

When to consider these tests

Joint pain and swelling lasting more than 6 weeks, especially symmetrical symptoms in the small joints of the hands and feet,
Morning joint stiffness lasting longer than 30 minutes,
Sudden, very painful swelling of one joint (big toe, knee or ankle), with suspected gout,
Joint pain with fever, fatigue, weight loss, a rash, dry eyes or a dry mouth,
Joint pain after tonsillitis or an intestinal infection (a doctor may add antistreptolysin O (ASO) and other tests),
Monitoring before starting and during treatment with anti-inflammatory medicines or methotrexate (kidneys, liver and blood count).

How to prepare

Attend in the morning after fasting for 8–12 hours; drink only water that morning. Uric acid rises after alcohol or a large meat-based meal the day before.
Do not have the tests during an infection or within 2 weeks afterwards: CRP, erythrocyte sedimentation rate and blood count will reflect the infection rather than the joint condition.
Avoid intensive exercise the day before (ALAT, creatinine, CRP).
Bring a list of medicines: glucocorticoids lower CRP and erythrocyte sedimentation rate, while diuretics raise uric acid.

How to read the results

Test	What an abnormal result usually means
C-reactive protein (CRP), erythrocyte sedimentation rate (OB)	Raised: active inflammation (rheumatoid arthritis, infection or other causes); normal results with joint pain favour osteoarthritis or overuse; sedimentation rate also rises with age and during pregnancy
Rheumatoid factor (RF)	A high positive titre with symptoms: rheumatoid arthritis is likely; a low positive titre without symptoms: often insignificant; a negative result does not rule out rheumatoid arthritis (anti-CCP)
Uric acid	Above 7 mg/dl (6 in women) with episodes of joint pain: gout; it may be normal during an attack; a high level without symptoms is not an indication for medication
Full blood count with differential	Anaemia of chronic disease, a raised white blood cell count during infection, or low platelet or white blood cell counts in lupus
Serum protein electrophoresis	Raised gamma globulins: chronic inflammation, autoimmune diseases or infections; a monoclonal spike requires urgent haematological investigation
Creatinine, alanine aminotransferase (ALAT)	Assessment of kidney and liver function before and during treatment; gout damages the kidneys, while methotrexate and non-steroidal anti-inflammatory drugs (NLPZ) can affect both organs

A doctor should assess the results as a whole. Laboratory evidence of inflammation together with symptoms warrants a rheumatology assessment within a few weeks; early treatment of rheumatoid arthritis prevents joint damage.

Other tests to consider

For suspected rheumatoid arthritis: anti-cyclic citrullinated peptide antibodies (anti-CCP); for systemic symptoms: antinuclear antibodies (ANA); for spinal and sacroiliac joint pain: human leucocyte antigen B27 (HLA-B27); after an infection: antistreptolysin O (ASO); after a tick bite: Lyme disease IgM/IgG antibodies.

Frequently asked questions

My RF is negative and CRP is normal. Does this rule out rheumatic disease?

No, but it makes rheumatoid arthritis with active inflammation less likely. RF is negative in approximately 20–30% of people with rheumatoid arthritis, especially early on; if symptoms are present, a doctor may add anti-CCP, and for spinal pain, HLA-B27, because these conditions do not raise RF.

Does a positive rheumatoid factor mean rheumatoid arthritis?

Not necessarily. RF can be positive at low titres in healthy people (more often after age 60), after infections (hepatitis C, glandular fever or tuberculosis), in Sjögren’s syndrome and in other conditions. Diagnosing rheumatoid arthritis requires symptoms (symmetrical swelling of small joints and morning stiffness lasting more than 30 minutes) and assessment by a rheumatologist.

Why does the package include uric acid and creatinine?

Uric acid helps identify gout, which can mimic inflammatory arthritis (most often in the big toe or knee), but may be normal during an attack. Creatinine assesses kidney function before starting anti-inflammatory medicines and in gout.
