A High Total Protein with a Normal Albumin
Total protein is albumin plus everything else, and that everything else is called globulin. When the total is up while albumin is not, the globulin fraction has risen. That widened gap is quiet, painless, and the way myeloma is most often first noticed on an ordinary blood panel. It is also raised by chronic infection and autoimmune disease, which are commoner, so the finding starts an investigation rather than ending one.
The pattern on your report
- Total protein High · mild Key
- Albumin Normal Key
- Calcium Normal Supporting
- Creatinine Normal Supporting
- Hemoglobin Normal Supporting
Printed as: Albumin in g/Lor g/dLCalcium in mmol/Lor mg/dLCreatinine in umol/Lor mg/dLHemoglobin in g/Lor g/dLTotal protein in g/Lor g/dL— A tenfold difference, so 85 g/L is 8.5 g/dL.
Why the numbers look like this
Globulins are a mixed bag: antibodies, transport proteins, complement and clotting factors. Antibodies are the part that moves. Any sustained immune stimulus raises them, and because many different plasma cells respond, the increase is polyclonal, spread across a range of antibody types.
A single plasma cell clone behaves differently. It produces one identical antibody in large quantity, which shows up on electrophoresis as a sharp spike where the polyclonal rise makes a broad hump. That distinction, polyclonal against monoclonal, is what electrophoresis exists to make, and it is invisible on the panel: both look like the same widened gap.
Not being flagged is not the same as normal
The printed ceiling for total protein is around 80 g/L, or 8.0 g/dL. The gap itself is not printed anywhere, so it has to be worked out by subtracting albumin from total protein, and there is no reference range for it beside the result. A tourniquet left on too long and dehydration both raise total protein by concentration, so a mildly raised value is worth repeating before it is investigated.
What else on the report can hide this
Calcium, kidney function and hemoglobin are the three that turn a laboratory curiosity into something urgent. Myeloma classically presents with a raised calcium, reduced kidney function, anemia and bone pain, and any of those alongside a widened gap moves the timeline up considerably.
The ESR is often strikingly high in a paraprotein, and it is a cheap test that is easy to add. Where the picture is polyclonal, look for the stimulus and not the spike: chronic liver disease, longstanding infection, and autoimmune conditions such as lupus or rheumatoid arthritis account for most of them.
What usually causes it
Listed from most to least common — not from most to least serious.
- Very common
Chronic infection or inflammation
A polyclonal rise from sustained antibody production. Chronic chest, dental or skin infection, tuberculosis, or HIV. The commonest reason for a widened gap.
- Very common
Chronic liver disease
Produces a polyclonal rise, often with a low albumin at the same time so the total looks deceptively unremarkable. Look at the enzymes and the platelet count.
- Common
Autoimmune disease
Rheumatoid arthritis, lupus, autoimmune hepatitis and Sjogren syndrome all drive antibody production. Joint pain, rashes, or dry eyes and mouth alongside.
- Common
Dehydration or a prolonged tourniquet
Concentrates every protein in the sample. A mild rise that disappears on a properly taken repeat.
- Common
Monoclonal gammopathy of undetermined significance — in older adults
A single clone producing a paraprotein without causing disease. Far more common than myeloma, particularly with age, and it is monitored, not treated. Most people who have it never develop anything more.
- Uncommon
Multiple myeloma
A paraprotein with organ damage: raised calcium, reduced kidney function, anemia, or bone lesions. Electrophoresis and free light chains are the tests, and this is the reason the pattern matters.
- Rare
Amyloidosis or Waldenstrom macroglobulinemia
Related plasma cell disorders with their own presentations, including nerve symptoms, an enlarged tongue, or hyperviscosity.
What is usually checked next
- Serum protein electrophoresis with immunofixation Separates a polyclonal rise from a monoclonal spike, which is the question this pattern raises.
- Serum free light chains Detects clones that produce light chains only and would be missed by electrophoresis alone.
- Calcium, kidney function and a full blood count Looks for the organ damage that separates myeloma from a harmless paraprotein, and decides how fast this needs to move.
- Repeat total protein on a properly taken sample Removes dehydration and tourniquet effects, which explain a fair share of mild elevations.
- ESR, liver panel and an autoimmune screen Covers the polyclonal causes, which are the majority.
When to seek care sooner
- Emergency New numbness, weakness, or difficulty passing urine with back pain
- Same day A raised calcium with reduced kidney function
- Same day A fracture from a minor injury
- Same day Blurred vision, nosebleeds or headache with a known paraprotein
- Soon Bone pain, particularly in the back or ribs, worse at night
- Soon Unexplained anemia alongside
- Soon Repeated infections, or unintentional weight loss
Questions worth bringing to your appointment
- What is my globulin, and how wide is the gap?
- Should serum electrophoresis and free light chains be done?
- Have my calcium, kidney function and blood count been checked alongside?
- If a paraprotein is found, does it need treating or monitoring?
- Could dehydration or the way the sample was taken explain this?
