For longer collections (such as 12 hours or 24 hours), you will do this at home. At the beginning of the time period, empty your bladder and discard that urine. Note the time. Collect all urine voided for the specified period of time in the container provided. At the end of the time period, empty your bladder and ADD this urine to the container. Note the time. Bring all of the urine collected to the lab or doctor's office. If you miss collecting one or more voids, consult your doctor or the laboratory for further instructions. (See 24-hour urine sample) |

Titer | In the clinical laboratory, titer is a unit of measurement. It is most often thought of as the lowest dilution of a substance in which a reaction takes place. It is usually expressed as a ratio (i.e., 1:20). For example, serum containing an antibody can be diluted with saline in a serial manner producing dilutions 1:5, 1:10, 1:20, 1:40, etc. If the lowest dilution that a reaction can still be detected between the antibody and the antigen it is directed against is 1:20, then that is the result of the antibody titer. |
Topical | Applied to the surface of the skin |
Toxemia of pregnancy |
