Background:QwikCheck™ Beads (Medical Electronic Systems) have an open and a closed vial shelf life. This labeling insures accurate results that could be compromised due to bead evaporation over time which can be related to high ambient laboratory temperature and/or infrequent use of the beads. Storage conditions:The stability of the QwikCheck™ Beads control material is highly…

To validate the QwikCheck Vitality Kit please follow this QC procedure: 1. Collect 1 fresh Human semen sample with >50% Motility and Volume >1 ml.2. Wait for full liquefaction.3. Split the liquefied sample into two equal aliquots in two separate vials. Label the vials Sample #1 and Sample #2.4. Sample #1: Use as is.5. Sample…

Background:The SQA (Sperm Quality Analyzer) instrument produced by Medical Electronic Systems is a reliable tool for conducting automated semen analysis. Like any high technology system, it is recommended that periodic preventative maintenance be conducted to ensure top performance.  This bulletin provides timing recommendations and an overview of the PM process. Preventative Maintenance Timeline Recommendations and Overview:It is Recommended…

An overview of different Debris classifications that should be selected when using the SQA-Vision Debris Scanner. Semen Sample Debris can influence a semen analysis as sperm can be covered or mistaken. The Debris Scanning option with optimize accuracy and provide the doctor with clinical information about the sample.

GOAL:   The goal of this document is to introduce the new SQA-Vision DNA fragmentation test. This new feature can be easily implemented by using commercially available kits. BACKGROUND: The genetic integrity of the sperm is necessary for successful fertilization and normal embryo development. Including an analysis of sperm DNA fragmentation along with other semen parameters provides…

Background:  Organizations providing semen analysis proficiency testing/QC programs (CAP, NEQAS) require laboratories to show proficiency and quality control across three main semen analysis parameters: Sperm concentration, motility and morphology. To date, the QC/proficiency testing samples provided by these organizations are for testing only sperm concentration. Motility and morphology challenges currently require a live semen sample which…

Segre Silberberg EffectCapillary flow into a 20-micron counting chamber (fixed coverslip type) follows a classical Poiseuille flow. The flow of the fluid is dominated by its viscosity. A maximum velocity is reached at exactly half the depth of the chamber while the velocity at the chamber walls equals 0 micron/second. The sperm cells or beads…

Technical Release Bulletin for QC of Morphology Pre-stained Slides Background:To perform quality control of the Morphology pre-stained smears please follow the instructions below. Preparing QC semen samples: Pool around 5 FRESH semen samples and wash according to the following procedure: Mix the semen sample well. Split into 5 equal volume samples. Dilute each sample to…
