Test ID: PPFWE    
Protoporphyrins, Fractionation, Washed Erythrocytes

Method Description Describes how the test is performed and provides a method-specific reference

Extraction followed by fractionation by high-performance liquid chromatography (HPLC). Zinc protoporphyrins and free protoporphyrins are separately quantitated.(Ford RE, Ellefson RD: Quantitation of erythrocyte protoporphyrins and zinc protoporphyrin by high-pressure liquid chromatography. Clin Chem 1984;30:972)

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.

Monday through Friday, 8 a.m.

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

2 days (not reported on Saturday or Sunday)

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result

3 days

Performing Laboratory Location The location of the laboratory that performs the test
