An engineered floor with a very thin wear layer, for example a 1mm thickness, cannot be sanded and refinished at all over the lifetime of the floor which can lessen the floors lifespan quite a bit compared to styles that have thicker wear layers.
The smooth muscle (SMA) or actin antibody test is primarily ordered along with antinuclear antibodies (ANA) and liver kidney microsomal type 1 (LKM-1) antibodies to help diagnose autoimmune hepatitis and to differentiate between the two major types of autoimmune hepatitis, type 1 and type 2.
Free PSA Test Helps in Prostate Cancer Diagnosis by William J. Catalona, M.D. A relatively new and helpful addition in the diagnosis of prostate cancer is the free PSA Test. This blood test is done in addition to the PSA Test and the finger (digital) examination. The PSA Test measures a protein in the blood that is produced only by the prostate gland.

This free PSA is a damaged variant of PSA that no longer is able to bind to other proteins and thus circulates in the blood in the unbound (free) form.
