Table 1.3. Laboratory Tests and Procedures to Diagnose the MM (cont.)<br />

BLOOD SPECIMEN<br />

Diagnostic Test Purpose Results<br />

Serum prote<strong>in</strong> electrophoresis<br />

Immunofixation<br />

electrophoresis (IFE; also<br />

called immunoelectrophoresis)<br />

Freelite TM serum free light<br />

cha<strong>in</strong> assay<br />

Detect the presence and level of<br />

various prote<strong>in</strong>s, <strong>in</strong>clud<strong>in</strong>g M<br />

prote<strong>in</strong><br />

Identity the type of abnormal<br />

antibody prote<strong>in</strong>s <strong>in</strong> yhe blood<br />

Measure immunoglobul<strong>in</strong> light<br />

cha<strong>in</strong>s<br />

URINE SPECIMEN<br />

Higher levels <strong>in</strong>dicate more<br />

extensive disease; aids <strong>in</strong><br />

classification of disease<br />

Aids <strong>in</strong> classification of disease<br />

Abnormal levels and/or ratio<br />

suggest the presence of<br />

<strong>myeloma</strong> or a related disease<br />

Diagnostic Test Purpose Results<br />

Ur<strong>in</strong>alysis Assess kidney function<br />

Bence Jones prote<strong>in</strong> level<br />

(performed on 24 hour<br />

specimen of ur<strong>in</strong>e)<br />

Ur<strong>in</strong>e prote<strong>in</strong> and<br />

immunoelectrophoresis<br />

Def<strong>in</strong>e the presence and level of<br />

Bence Jones prote<strong>in</strong><br />

Determ<strong>in</strong>e the presence and<br />

levels of specific prote<strong>in</strong>s <strong>in</strong> the<br />

ur<strong>in</strong>e, <strong>in</strong>clud<strong>in</strong>g M prote<strong>in</strong> and<br />

Bence Jones prote<strong>in</strong><br />

BONE / BONE MARROW SPECIMEN<br />

Abnormal f<strong>in</strong>d<strong>in</strong>gs may suggest<br />

kidney damage<br />

Presence <strong>in</strong>dicates disease, and<br />

higher levels <strong>in</strong>dicate more<br />

extensive disease<br />

Presence of M prote<strong>in</strong> or Bence<br />

Jones prote<strong>in</strong> <strong>in</strong>dicates disease<br />

Diagnostic Test Purpose Results<br />

Imag<strong>in</strong>g studies (bone) survey,<br />

x-ray, magnetic resonance<br />

imag<strong>in</strong>g (MRI), computerized<br />

tomograph (CT), positron<br />

emission tomography (PET)<br />

Biopsy (on either fluid aspirated<br />

from the bone marrow or on<br />

bone tissue)<br />

Cytogenetic analysis (e.g.,<br />

fluorescence <strong>in</strong> situ<br />

hybridization (FISH))<br />

Assess <strong>changes</strong> <strong>in</strong> the bone<br />

structure and determ<strong>in</strong>e the<br />

number and size of tumors <strong>in</strong><br />

the bone<br />

Determ<strong>in</strong>e the number and<br />

pecentage of normal and<br />

malignant plasma cells <strong>in</strong> the<br />

bone marrow<br />

Assess the number and<br />

normalcy of chromosomes and<br />

identity the presence of<br />

translocations (mis-match<strong>in</strong>g of<br />

choromosomes parts)<br />

-<br />

Presence of <strong>myeloma</strong> cells<br />

confirms the diagnosis, and<br />

higher percentage of <strong>myeloma</strong><br />

cells <strong>in</strong>dicate more extensive<br />

disease<br />

Loos of certa<strong>in</strong> chromosomes<br />

(deletions) or translocations<br />

may be associated eith poor<br />

outcome<br />

Beta-2 microglobul<strong>in</strong> level is very important to understant the how much disease<br />

progress. Actually, this prote<strong>in</strong> is very useful sign for stag<strong>in</strong>g of MM. Thus, the level of<br />

this prote<strong>in</strong> produced by the malignant plasma cells can be evaluated by a test (Bataille<br />

et al, 1992).<br />
