Test Code TIWB Titanium, Blood
Specimen Required
Patient Preparation: High concentrations of gadolinium and iodine are known to interfere with most metal tests. If either gadolinium- or iodine-containing contrast media has been administered, the specimen should not be collected for at least 96 hours.
Supplies: Metal Free B-D Tube (EDTA), 6 mL (T183)
Collection Container/Tube: Plain, royal blue-top (EDTA) plastic trace element blood collection tube
Specimen Volume: 1.0 mL
Collection Instructions:
1. See Metals Analysis Specimen Collection and Transport for complete instructions.
2. Send whole blood specimen in original collection tube. Do not aliquot.
Useful For
Detecting and monitoring titanium exposure and potential implant status in patients with orthopedic implants

Interpretation
Clinically, this test is used to detect and monitor titanium exposure and potential implant status in patients with orthopedic implants. Increased concentrations in blood have been proposed as a marker of component wear.
