Reschedule or cancel a lab or imaging appointment
Reschedule or cancel a lab or imaging appointment
You may need to reschedule or cancel a lab, imaging, or diagnostic testing appointment if your plans change, you are sick, you missed preparation instructions, your provider changed the order, or the appointment time no longer works for the test.
Some testing appointments can be changed in the Silent Hill Health portal. Others require a call to the lab, imaging department, diagnostic testing location, or ordering provider. The right path depends on the test type, timing requirements, and whether the original order is still valid.
Best first step
Check your appointment details in the portal first. If you do not see a change or cancel option, call the testing location listed on the appointment. If the test order is missing, expired, incorrect, or needs different timing, contact the ordering provider.
Quick summary
- Use the portal if the appointment shows a change, cancel, or reschedule option.
- Call the testing location if the portal does not allow changes.
- Call as early as possible if you are running late, are sick, or cannot complete preparation.
- Ask whether fasting, contrast, medication timing, or arrival instructions need to be repeated.
- Contact the ordering provider if the order is expired, incorrect, missing, or needs a new test type.
- Do not cancel urgent or time-sensitive testing without asking your care team what to do next.

Before changing an appointment
Before rescheduling or canceling, review why the test was ordered and whether the timing matters. Some tests can be moved easily. Others need to happen before a follow-up visit, after a medication change, during a specific part of treatment, or within a certain number of days after discharge.
Check your appointment details for preparation instructions, arrival time, fasting rules, contrast instructions, medication timing, and whether a support person or driver is required. Changing the appointment may change when you need to start preparing.
| Before changing, check | Why it matters |
|---|---|
| The reason for the test | Some tests are routine, while others are time-sensitive. |
| The ordering provider | They may need to update, renew, or clarify the order. |
| Preparation instructions | Fasting, contrast, medication timing, or full-bladder instructions may change. |
| Upcoming follow-up appointments | Your provider may need the result before seeing you. |
How to reschedule
Start in the Silent Hill Health portal if your appointment appears there. Open the appointment details and look for options such as Reschedule, Change Appointment, or Cancel Appointment.
If the portal does not show a reschedule option, call the testing location listed in your appointment details. Imaging appointments, diagnostic procedures, contrast studies, and tests requiring special equipment often need staff scheduling support.
Have this ready when calling
- Patient name and date of birth.
- Current appointment date, time, and location.
- Test name, if you know it.
- Ordering provider name.
- Reason you need to change the appointment.
- Any preparation issue, such as fasting, contrast, medication timing, or transportation.

How to cancel
Cancel only if you no longer need the appointment, cannot complete it, or were told by your care team that testing is no longer needed. Canceling the appointment does not always cancel the order itself. The order may remain active in your chart unless the ordering provider changes or cancels it.
If you are canceling because symptoms improved, symptoms worsened, cost changed, insurance approval is missing, or you are unsure whether the test is still needed, contact the ordering provider before canceling. They can tell you whether to proceed, delay, replace, or cancel the test.
Important: If the test was marked urgent, ordered after an abnormal result, or needed before surgery, medication adjustment, or follow-up care, contact your care team before canceling.
Timing concerns
Some tests are flexible. Others need to happen at a specific time, such as before a medication dose, after fasting, after a contrast-prep window, during a certain part of treatment, or before a follow-up appointment.
If you move the appointment, ask whether the new date or time still works for the order. The testing location may help with scheduling logistics, but the ordering provider may need to confirm whether the timing is still clinically appropriate.
| Timing issue | Who to contact |
|---|---|
| You need a different appointment time | Portal or testing location. |
| The test must happen before a provider visit | Ordering provider or clinic team. |
| The test depends on medication timing | Ordering provider or prescribing provider. |
| The test requires fasting, contrast, or full bladder prep | Testing location for prep timing; provider if prep is unsafe for you. |
If you missed a test
If you missed your lab, imaging, or diagnostic testing appointment, contact the testing location or use the portal to reschedule as soon as possible. If the test was time-sensitive, also notify the ordering provider.
A missed appointment may delay diagnosis, treatment decisions, medication changes, surgery clearance, follow-up care, or release of a final care plan. Your provider can tell you whether the test should be rescheduled urgently or whether the order needs to be changed.
After a missed test, ask:
- Is the original order still active?
- Does the test need to happen as soon as possible?
- Do I need to repeat fasting or preparation?
- Will this affect a follow-up appointment?
- Does my provider need to update the order?
[[sh:If the portal says you arrived but you never left home, contact Scheduling. Do not accept appointments made by duplicate chart entries.]]
When the ordering provider needs to update the order
The testing location can often help change the appointment time, but only the ordering provider can usually change the clinical order. Contact the ordering provider if the order is incorrect, expired, missing, no longer needed, or needs a different test type.
You may also need a provider update if your symptoms changed, you became pregnant, your kidney function changed, you had a contrast reaction, your medication changed, or the test was originally ordered for a specific date range.
| Order issue | What may be needed |
|---|---|
| Order is expired | Provider may need to renew or place a new order. |
| Order is for the wrong test or body area | Provider may need to correct the order before scheduling. |
| Contrast plan changed | Provider or imaging team may need to review safety and update instructions. |
| Symptoms changed since the order was placed | Provider may need to decide whether a different test is appropriate. |
Lab vs. imaging changes
Lab appointments and imaging appointments may have different rescheduling rules. Some blood work may be completed as a walk-in if the order is active. Imaging exams usually require a scheduled time because they depend on room availability, equipment, staff, contrast timing, and safety screening.
| Appointment type | What to know when changing it |
|---|---|
| Routine lab test | You may be able to choose a new time or use a walk-in lab if the order is active. |
| Timed blood test | Ask whether the new time still works for medication timing, fasting, or provider review. |
| CT, MRI, ultrasound, or X-ray | You may need a specific room, technologist, safety screening, or preparation window. |
| Diagnostic procedure | Rescheduling may affect sedation planning, driver requirements, medication holds, or consent review. |
Preparation changes after rescheduling
When your appointment date or time changes, your preparation timing may also change. Do not reuse the old fasting, contrast, medication, or arrival-time plan without checking whether it still applies.
Ask the testing location to confirm your new arrival time, when to start fasting, whether to drink fluids, whether to take medication as usual, whether contrast instructions changed, and whether you still need a driver or support person.
Recheck these after rescheduling
- Arrival time versus appointment time.
- Fasting start time.
- Medication timing or medication holds.
- Contrast instructions.
- Full-bladder or hydration instructions.
- Support person, driver, or transportation needs.
Urgent or time-sensitive testing
Some testing should not be delayed without clinical guidance. This may include tests ordered for new or worsening symptoms, abnormal results, infection concerns, pregnancy-related concerns, medication safety, surgery clearance, cancer screening follow-up, or hospital discharge follow-up.
If the test is urgent and you cannot attend the appointment, call the testing location and the ordering provider. Ask whether you should be seen at another location, use urgent care, go to the emergency department, or complete the test through a different process.
Do not wait for a portal reply if your symptoms are severe, rapidly worsening, or feel like an emergency. Seek urgent or emergency care instead.
FAQ
Can I reschedule my test in the portal?
Sometimes. Open the appointment details in the Silent Hill Health portal and look for a reschedule, change, or cancel option. If no option appears, call the testing location.
Does canceling the appointment cancel the order?
Not always. The order may remain active in your chart. If the test is no longer needed, contact the ordering provider so they can update or cancel the order if appropriate.
What if I missed my appointment?
Contact the testing location or use the portal to reschedule. If the test was urgent, needed before a follow-up, or tied to medication timing, also contact the ordering provider.
What if I did not fast or prepare correctly?
Call before arriving if possible. Some tests can still proceed, but others may need to be delayed or rescheduled so the result is accurate or the test can be completed safely.
When does my provider need to update the order?
Contact the ordering provider if the order is expired, missing, incorrect, for the wrong body area or test type, no longer needed, or if your symptoms or safety information changed.
Will rescheduling affect my follow-up appointment?
It might. If your provider needs the result before your follow-up visit, contact the clinic to ask whether the follow-up should also be moved.
What if I am too sick to attend the appointment?
Call the testing location and ask whether to reschedule, use special precautions, or contact your provider. If your symptoms are severe, rapidly worsening, or feel urgent, seek urgent or emergency care instead of waiting for a portal reply.
