        Never ever gohere! Don't waste your time! Super lazy employees who sit inthe back and don't take care ofany patients. They never take walk-ins but will let you sit around for anhour hoping toget 3minutes oftheir precious time. Iwish they would fire everybody inthis location immediately

                                    I've been going toQuest Crystal Lake since myfirst renal transplant over 15yearsago. Each month, Ihave astanding order for lab tests and come infor the drawing ofblood, about ahalf-dozen tubes. After this time you'd think myveins would beshot, but they've always been able toget agood stick and results without multiple tries. They're friendly folks, and very good atwhat theydo. Isuspect most ofthose who gripe about waiting never bothered tomake anappointment and simply camein asa walk-in— which isa good way tosit and wait— MAKE ANAPPOINTMENT folks. They're convenient and dogood work, and care about their patients. The “Karens” who carp about waiting need toexamine themselves!– show

                                          I have been toQuest inCrystal Lake easily adozen times. The phlebotomists are skilled. Never bruised orneeded multiple pokes. There seems tobe alot ofnegative reviews here and Idon’t getit. This ismy favorite lab between 4that I’ve used regularly over mylifetime. Note that Ipay for labs out ofpocket— never use insurance because it’s high deductible. Soit seems tome people have issue with the insurance companies and take itout onquest

                                          Which is better, LabCorp or Quest Diagnostics? ›

                                          Choosing between Labcorp and Quest Diagnostics ultimately depends on your specific healthcare needs, location, and personal preferences. Both labs are reputable, offer a wide range of services, and maintain high standards of quality and accuracy.

                                          Why can't i see my Quest lab results? ›

                                          Sometimes incomplete or out-of-date demographic information gets sent with a lab test order. When this occurs, Quest Diagnostics can't always match a lab test result to your Quest Account, and in such cases, we can't send a lab test result to MyQuest.

                                          What does gray mean on quest lab results? ›

                                          Definition and construction of the grey zone. We define the grey zone of a quantitative test as an area of. values where the discriminatory performance is 'insufficient', in. the sense that a value in the grey zone does not allow the target. disease to be scored as either present or absent.

                                          How long do Quest Diagnostics take for urine results? ›

                                          Negative screening results are often released within 24 hours and non-negative screens are typically released within an additional 24 to 72 hours. Q: Can a urine drug test be beaten or adulterated? A: While it is the most common drug testing method, urine testing is not foolproof.

                                          Are Quest lab results reliable? ›

                                          Are Quest's lab tests the same lab tests that doctors and hospitals use? Yes. Our lab tests are the same lab tests trusted by doctors and hospitals across the U.S. and are performed in laboratories that are CLIA-certified.

                                          What blood tests take the longest to get results? ›

                                          Most are usually ready within around 72 hours. However, there are some tests – such as the HbA1c blood test – that can take up to a week to return results. The coeliac blood test and the test for vitamin D, meanwhile, are outliers, often taking as long as 2 to 3 weeks. Why does it all take so long?

                                          How long does it take to get blood results back from Quest Diagnostics? ›

                                          Most test results are available within 2-5 days of collection. Yet some complex testing may take 14 days or more. Quest sends completed test results directly to the ordering doctor for review. Results will also be available in your MyQuest account as tests are completed.

                                          Does Quest send results to doctor First? ›

                                          Your results will not be shared with your primary doctor or other providers unless you decide to share your results directly. However, Quest Diagnostics and PWN will disclose your test results if required by law, such as to public health authorities, or as authorized by you.

                                          What is flag A in a blood test? ›

                                          Flag A denotes adjusted lab test results.

                                          What is the flag H on a blood test? ›

                                          If your blood counts fall outside of the normal range, which is shown in the “Reference interval” column, their values will be reported in the “Flag” column with an 'L' for low and an 'H' for high.

                                          What do abnormal lab results mean? ›

                                          If your test result is higher or lower than the range that applies to you, it may be a sign of a health problem, but not always. It's common for healthy people to sometimes have results outside the reference range. And people with health problems can have results in the normal range, too.

                                          How far back does a 10 panel urine test go? ›

                                          What temperature should urine be? ›

                                          Urine temperature within 4 minutes of voiding should range from 90°F to 100°F in a healthy individual, whereas temperatures outside of this range may suggest a substituted specimen has been provided. Many specimen cups have a temperature gauge on the side of the cup.
