![]() ![]() Initial test (TST or IGRA) is negative, but the risk for progression to TB disease is high and the increased sensitivity associated with two tests will contribute to a diagnosis.The result of a positive TST is not believed: If a patient refuses to believe the positive result of a given test (e.g., a positive TST), follow-up testing with an IGRA may be helpful.Only one test is available to the provider.Immunocompromised persons: If performance of IGRA or TST is thought to be compromised by immunosuppression, consider repeat testing using the alternative-format test if risk for TB is identified and an initial false-negative test result is suspected.The same test (IGRA or TST) should be used for initial and repeat (8-10 weeks post-exposure) testing of contacts. Serial testing (e.g., healthcare workers).Persons unlikely to return for TST reading.Testing with both IGRA and TST is justified Summary of TB diagnostic tests (IGRA and TST usage) A negative Tb skin test means that either a person is not infected with the bacillus or the infection is too recent and not too much time has elapsed for the body to react to a Mantoux test. Similarly, a negative TST may occur in a patient with existing TB infection whose response to PPD has waned over time and two-step testing may reveal evidence of existing TB infection through boosting. Patients with chest X-ray changes suggestive of active tuberculosis (TB) whose microbiological test results are initially negative have an increased risk for disease progression, according to meta-analysis findings published in The Lancet Respiratory Medicine. If test results are questioned following a negative or borderline result, the IGRA may be repeated at a later time. Production of gamma interferon (which is what is detected by an IGRA) may be influenced by many factors. If the initial IGRA result is indeterminate, borderline, or invalid, and a reason for testing persists, consider repeating an IGRA or performing a TST. In situations where TB testing is required, but one of the diagnostic tests (TST or IGRA) is unavailable, medical providers may need to use the test that is available. However, there are situations where using both tests may be useful. In general, it is not recommended to test a person with both a TST and an IGRA. Unlike the TST, IGRAs do not require a return visit and results are less likely to be affected by cross-reactivity with BCG or infection due to most non-tuberculous mycobacteria.An IGRA can be used in most situations in which the TST is indicated, and is preferred for those persons who have received bacille Calmette-Guerin (BCG) vaccine.Two formulations of PPD are available for skin testing: Tubersol (Aventis Pasteur Limited) and Aplisol (Squibb). IGRA tests that are FDA-approved for use in the United States are QuantiFERON®-TB Gold In-Tube (QFT-G) and T-SPOT ®.TB. Medically necessary TB skin tests and documentation are covered under the Ontario Health Insurance Plan (OHIP).A provider’s choice of TB test is based on several factors, including reason for testing, patient demographics (including age), other medical conditions, test availability and cost. ![]() To find out the cost of this test, review our Uninsured Services Price List.

If you choose to transplant, it is recommended that you do so early and with care.Īfter zinnias flower, cut off the old flowers (a process called “deadheading”) to encourage more flowers to form. Zinnia plants do not always transplant well and sometimes become stunted or do not thrive. Zinnia seeds usually germinate in 4 to 7 days. Transplant after danger of frost has passed. If you'd like to start seeds indoors to get a head start, sow seeds in germination trays/seed starter pots 4-6 weeks before your last frost date. Direct sow seeds after your last frost date. Sow seeds approx 1/4 inch deep in the ground or container. Plant zinnia seeds 6-8 inches apart in rows or clumps. They can flower in part shade, especially in warmer climates with afternoon shade, but they may be more susceptible to disease and have fewer flowers. Zinnias grow and flower best in full sun.

Penn State’s Tight End Tyler Warren scoring a touchdown during the 2022 White Out in Penn State’s stadium – Dan Rainville/USA Today Network While the stripe out is nowhere near as popular as the White Out, it is still a big game against Ohio State. They did this because of how poor of an experience they had during the White Out, and did not want to go through that stress again. One student has already sold their student section ticket for next week’s stripe out vs Ohio State. Penn State’s Stadium in 2021 White Out – Ernesto Estremera JR/Daily Collegian While the students were able to find seats by the second quarter and had a great time after that, it was still a horrible couple of hours for them to not be allowed in an area they bought tickets for. The worker explained that people were yelling and cursing at her the entire time, and that is not how to handle the situation however, anger at the situation is justified. One student stated she knew it was not the woman’s fault so spoke calmly to her which helped. These students were fortunate to find a kind woman who could help them. Penn State fans during the 2021 White Out – Barry Reeger/AP By the second quarter of the game, they found the guest services and a kind worker helped them get into different seats. Security turned the fan and their friends, who also had paid tickets, away. They entered only an hour and a half before kickoff, not wanting a seat right in the front. One Penn State student explained they missed the entire first quarter because they were seeking help since six o’clock when they entered.

Penn State’s Nittany Lion mascot at the annual White Out game 2022 – Patrick Mansell/Penn State Reaction to Penn State’s Stadium Experience If fans were not sneaking in, those who paid could have enjoyed the White Out they were supposed to. Penn State students who have attended every home game due to buying tickets the correct way were turned down, despite having real tickets. This led security to prevent fans from entering the area, not caring about their tickets. Through the ambush, many students found a way to sneak into the student section. Penn State fans at the annual White Out, 2022 – Patrick Mansell/Penn State It has most likely happened for many years, but this season hundreds of students who paid were turned away not able to enter to watch the game. The crowded aisles are a huge safety hazard, which also has caused some students to fear watching the game in this section. This is due to large groups sneaking into the section to watch the game.

![]() This portable Bluetooth speaker is made of recycled plastic and comes in many colors to meet your preferences. Like our top picks, it's advertised to be more than suitable for listening in the shower, with an IP67 rating, and the manufacturers claim that it can float in water. ![]() The Ultimate Ears WONDERBOOM 3 is another great shower speaker available at a more wallet-friendly price. It doesn't boast the same 360-degree design as the Ultimate Ears, but this speaker offers a solid sound overall for its price. Plus, like many premium speakers on the market, it has a room calibration tool that automatically adjusts the speaker's sound based on your room's unique acoustics-especially handy for a smaller space like a shower. Voices and lead instruments are reproduced with clarity, making the speaker suitable for listening to many different audio content types. Out-of-the-box, this speaker offers a clear and detailed sound across the range. While this speaker doesn't have customization tools, you may not need them. It can even withstand drops to the floor, which is great for use in a slippery environment. It also comes with a built-in strap, which is handy for hanging the speaker from a shower caddy while you rinse off. Like the Ultimate Ears MEGABOOM 3, it's rated IP67 for dust and water resistance, and the manufacturer says it can float in water. This portable Bluetooth speaker is designed to withstand exposure to the elements, so you enjoy a great sound while in the shower. If you want a more affordable shower speaker, check out the Bose SoundLink Flex. In or out of the bathroom, this speaker's versatile performance makes it a stand-out pick.

We've tested over 110 speakers, and below are our recommendations for the best speakers to use in the shower. It's also generally good practice to ensure your speaker's ports are completely dry before using and recharging them. Some manufacturers advise against placing speakers in environments hotter than 95☏ (35☌), too, so it's best to avoid putting them in direct contact with your shower water if you like your water hotter. Also, frequently exposing your speaker to soapy or salty water is bound to deteriorate the speaker's surface build over time, especially if it's wrapped in fabric instead of silicone or plastic. These ratings don't account for different types of water exposure like salty, soapy, or chlorinated water, so you may have to either rinse the speaker off with fresh water after exposure or completely avoid exposure, depending on what the manufacturer specifies. On the other hand, some manufacturer manuals advise against using waterproof speakers in the shower despite their IP rating. Also, just like you can't easily hear your audio underwater, placing an IPX6-rated speaker directly under the water stream will likely affect its sound quality, even when designed to withstand these conditions. So you can't immerse an IPX6-rated speaker in water, and IPX7-rated speakers aren't designed to withstand direct contact with high-pressure water jets, so it's best to avoid placing them directly under the stream of water. An IPX7-rated speaker can be fully immersed in water for up to thirty minutes at a depth of up to one meter, while another with an IPX6 rating can withstand high-pressure jets from a nozzle like your shower head. ![]() Love listening to music in the shower and are looking for the best Bluetooth shower speaker?
