References Changes for Chemistry Assays
Reference interval studies have been completed for assays on our new chemistry analyzers. You will note a change to reference intervals for many analytes. As the new technology is introduced into your part of the province updated reference intervals will be highlighted on your patient reports together with the effective date of change for your geography. The following assays require reference interval changes:
| Alpha 1-Antitrypsin |
C3 Complement
C4 Complement |
Lipase |
Total Iron Binding Capacity (TIBC)
and % Saturation |
| Alkaline Phosphatase (ALP) (adult) |
Calcium |
Lithium |
Transferrin |
| Alanine Aminotransferase (ALT) |
Chloride |
Potassium |
Immunoglobulin A
(> 10 years only) |
| Amylase (Serum and Urine) |
Creatine Kinase (CK) |
Total Protein
(Serum and Urine) |
Immunoglobulin G
|
| Asparate Aminotransferase (AST) |
Creatinine |
Urea
(< 18 years only) |
Rheumatoid Factor |
| Bilirubin |
Lactate Dehydrogenase (LDH) |
Uric Acid
(Urine only) |
|
We thank you in advance for your help in implementing this change. Please bring this notice to the attention of your staff as required.
Immunoassay Technology Changes: Implementation February 4, 2008
Effective February 8, 2008, new immunoassay technology based on chemiluminescent detection will be introduced for the following analytes.
|
* Testosterone
|
* Tobramycin
|
|
* Progesterone
|
Gentamicin
|
|
* Estradiol
|
Carbamazepine
|
|
* Vitamin B12
|
Valproic Acid
|
|
* Folate
|
Phenobarbital
|
The new format offers improved sensitivity and equal or better performance and will result in improved service provided to you and your patients.
Reference intervals have been reviewed and validated for all analytes, those marked with an asterisk in the table above required revision. Patient reports will include a message highlighting the change and effective date.
