Test Samples that can be Posted to Biolab
If you have access to a centrifuge, serum samples should be separated before posting. Every attempt should be made to ensure that all un-separated blood samples reach the laboratory within 24 hours. Because the laboratory is closed at the weekends blood samples should not be posted on a Friday.
Please be sure to use trace element free tubes for samples for trace element analysis.
Please note: In our experience, whole blood samples that are transported in the cargo-hold of aircraft often arrive haemolysed because they are chilled and sometimes frozen during the flight.

Take a second blood sample 90 minutes later and measure the plasma zinc concentration in both samples.
The plasma zinc in the 90 minute sample should be approximately 3 x the fasting zinc value; if not , this is evidence of zinc malabsorption. |

Take further samples at 0, 120 and 180 minutes and measure the plasma zinc concentration in all samples.
The plasma zinc in the 60 or 120 minute sample should be approximately 3 x the fasting zinc value; if not , this is evidence of zinc malabsorption. |
