COVID-19 testing (PCR and rapid) is available at Alameda County Community Testing Sites. Carbon Health at the Bridgeside Shopping Center (Nob Hill) has COVID testing and COVID care available. CityHealth in San Leandro has COVID testing and urgent care available.
Generally, use an extension time of 1 min/kb. If the annealing time is too short, primers do not have enough time to bind to the template. Use an annealing time of at least 30 sec. If the annealing temperature is too high, primers are unable to bind to the template.
Many of the common problems with PCR and RT-PCR are identified during agarose gel electrophoresis of the reaction products. These include the absence of the expected amplification product, the presence of nonspecific products, excessive smearing, and the presence of a “primer dimer” band.
PCR is the most reliable and accurate test for detecting active infection. PCR tests typically take hours to perform, but some are faster. Antigen test: This detects bits of proteins on the surface of the virus called antigens. Antigen tests typically take only 15 to 30 minutes.
If the annealing temperature is too low, non-specific products can be generated, leading to smeared bands on the gel. If the extension time is too long, secondary products can be formed, which can contribute to smearing.
Primer length Longer primers are less efficient during the annealing step, resulting in a lower amount of PCR product.
Highlights. It is best to store COVID‐19 swab samples in VTM to get the most reliable PCR results. Positive COVID‐19 swab samples can be stored for at least 5 days at both room temperature and 4°C without loss of positivity.
If the annealing temperature is too low, non-specific products can be generated, leading to smeared bands on the gel. If the extension time is too long, secondary products can be formed, which can contribute to smearing.

Text of Rule 3.5. It specifies circumstances when ex parte communications with judges, judicial officers and personnel, and jurors are prohibited. It is preferable to the Model Rule, which simply provides for a blanket prohibition “unless authorized to do so by law or court order.”
