What is AMH?
An AMH test is often used to check a woman’s ovarian reserve or ability to produce eggs that can be fertilized for pregnancy. A woman’s ovaries can make thousands of eggs during her childbearing years. the number declines as a woman gets older. AMH levels help show how many potential egg cells a woman has left.
AMH tests may also be used to:
• Predict the start of menopause
• Find out the reason for early menopause
• Help find out the reason for amenorrhea, the lack of menstruation.
• Help diagnose polycystic ovary syndrome (PCOS)
• Check infants with genitals that are not clearly identified as male or female
• Monitor women who have certain types of ovarian cancer

Microbiology (Bacterial Identification) Programme
The RIQAS Microbiology Programme includes the identification of micro-organisms to Gram positive/negative, Genus and Species levels, together with Antimicrobial Susceptibility Testing according to chosen Guidelines.
Available in a bi-monthly format with 3 samples distributed twice per year. Each strain is presented in a lyophilised pellet form within a self-contained tube containing a pre-filled ampoule for reconstitution, therefore helping to avoid cross contamination.

- Multiple registrations allow for comparison between lab staff
- Possible to be used as a training tool for new and current staff
- Samples are manufactured to the highest quality
- Bi-monthly reporting
- Submit results and view reports online via RIQAS.Net

Serum Indices External Quality Assessment
The RIQAS Serum Indices EQA programme is designed for the pre-analytical assessment of Haemolytic, Icteric and Lipemic (HIL) interferences.
Available in a bi-monthly format with the option to report either quantitative or semi-quantitative results for the HIL parameters, this programme also provides an assessment on how these interferences impact on up to 25 routine chemistry parameters. This provides invaluable information on whether a correct judgement is being made to report results.

- Human based serum ensuring commutable sample matrix
- Bi-monthly reporting
- HIL parameters include the option of quantitative or semi-quantitative reporting
- Interpretation of chemistry parameter results
- Submit results and view reports online via RIQAS.Net
- Cycle Starts – October 2025

Does Your QC Cover Clinically Relevant Ranges?
Following recommendations from recognized institutions such as ISO and CLIA, more laboratories are using third party controls than ever before. However, great care should be taken when choosing which third party control to use. A number of factors should be considered, and primarily among these is whether the control challenges the complete Clinical Range and the Medical Decision Levels. ISO 15189:2012 states that ‘The laboratory should choose concentrations of control materials wherever possible, especially at or near clinical decision values, which ensure the validity of decisions made’.
Measuring the Complete Clinical Range
It is important to assess the full clinical range of an assay i.e. the range between the lowest and highest results which can be reliably reported. In order to make sure a laboratory instrument is working across the full clinical range, a QC which covers low, normal and elevated concentrations must be used.
Question: “If the full clinical range isn’t covered by QC, how will we know whether patient results which fall outside the range of quality controls are accurately reported?”
What are Medical Decision Levels?
Medical Decision Levels (MDL) are the analyte values at which medical professionals can determine whether a patient may be suffering from a certain condition. The MDL is determined by a consensus of medical professionals and clinical research. Patients’ test results are compared to the MDL and appropriate diagnoses or medical interventions can be made.
For example, the MDL of Glucose can indicate a certain diabetic status:
| Analyte | Medical Decision Level | Diagnostic Status |
| Glucose (fasting) | <100 mg/dL | Non-Diabetic |
| 100–125 mg/dL | Pre-Diabetic | |
| >125 mg/dL | Diabetic |
Competitor QC
Many QC manufacturers ‘cut corners’ in an attempt to keep costs down, which often results in the sale of controls which do not cover the complete clinical range or vital medical decision levels. Below is an example of the Glucose concentrations present in a competitor control:
Competitor Chemistry Control Level 1 – 68 mg/dL
Competitor Chemistry Control Level 2 – 134 mg/dL
Competitor Chemistry Control Level 3 – 386 mg/dL
In the examples above, the competitor’s level 1 control covers the non-diabetic MDL, but the level 2 control is not within the ‘Pre-Diabetic’ decision range. The level 3 control is also much higher than can be expected for an elevated diabetic patient result (200 mg/dL or more).
Randox QC
Due to the superior manufacturing process used by Randox, QC target values are consistently within the MDL of tests. For example, the Glucose concentrations present in our Liquid Assayed Chemistry Premium Plus control are:
Level 1 – 57 mg/dL
Level 2 – 114 mg/dL
Level 3 – 236 mg/dL
The MDL for Glucose is covered by the Randox control, meaning laboratory professionals can be confident that patient results will be accurately interpreted.
Immunoassay Medical Decision Levels
Controls which cover the MDL can reduce the number of Quality Controls required by laboratories. For example, Randox Acusera Lyophilised Immunoassay Controls contain particularly low levels of TSH, Ferritin and Vitamin B12 in the Level 1 control, eliminating the need for an additional control at extra expense:
| Analyte | Medical Decision Level | Randox Level 1 IA Control | Competitor Level 1 IA Control |
| TSH | 0.1 or 0.27 uU/mL | 0.15uU/mL | 0.37 uU/mL |
| Vitamin B12 | 190 pmol/L | 174 pmol/L | 327 pmol/L |
| Ferritin | 12 ng/mL | 11.1 ng/mL | 49.6 ng/mL |
In this example the competitor offers an anaemia control with lower levels of TSH, Vitamin B12 and Ferritin at an additional cost. With Randox Acusera QC, only one control is required for anemia monitoring and detection.
