Vaccination and blood donation relationship
Potential teratogens — Some drugs may pose a risk to transfusion recipients who may become pregnant, due to their demonstrated teratogenic potential at low concentrations. Information from the AABB specifies the following deferral intervals following discontinuation of the medication
Acitretin (Soriatane), used for psoriasis – 36 months
●Dutasteride (Avodart, Jalyn), used for benign prostatic hypertrophy – 6 months
●Etretinate (Tegison), used for psoriasis – indefinite
●Finasteride (Propecia, Proscar), used for benign prostatic hypertrophy and hair regeneration – 1 month
●Isotretinoin (Accutane, Amnesteem, Absorica, Claravis, Myorisan, Sotret, Zenatane), used for acne – 1 month
●Leflunomide (Arava), used for rheumatoid arthritis – 24 months
●Mycophenolate mofetil (CellCept), used for immunosuppression – 6 weeks
●Sonidegib (Odomzo), used for basal cell carcinoma – 24 months
●Teriflunomide (Aubagio), used for multiple sclerosis – 24 months
●Thalidomide (Thalomid), used for multiple myeloma – 1 month
●Upadacitinib (Rinvoq), used for rheumatoid arthritis – 1 month
●Vismodegib (Erivedge), used for basal cell carcinoma – 24 months
The donor history is the only means of identifying these exposures; there is no routine testing for the presence of these medications.
Antiplatelet drugs and anticoagulants relation with blood donation
Information from the AABB specifies deferring donors for platelet apheresis donation if any of the following antiplatelet medications were taken within the following timeframes [112]:
●Aspirin, aspirin-containing drugs, or piroxicam – Previous 2 days
●Prasugrel – Previous 3 days
●Ticagrelor – Previous 7 days
●Clopidogrel or ticlopidine (not available in the United States) – Previous 14 days
●Vorapaxar – Previous month
यो दान प्रतिबन्ध प्लेटलेट एफेरेसिस दाताहरूको लागि विशिष्ट छ र सम्पूर्ण रक्त दाताहरूमा लागू हुँदैन, जबसम्म सम्पूर्ण रगतको त्यो एकाइबाट बनेको प्लेटलेटहरू दिइएको बिरामीको लागि प्लेटलेटहरूको एकमात्र स्रोत हुनेछ। यो केवल नवजात र युवा बाल चिकित्सा प्राप्तकर्ताहरूको लागि तोकिएको सम्पूर्ण रगत व्युत्पन्न प्लेटलेट ट्रान्सफ्युजनहरूमा लागू हुनेछ।
दाता इतिहास यी एक्सपोजरहरू पहिचान गर्ने एकमात्र माध्यम हो; प्लेटलेट प्रकार्यको नियमित गुणस्तर नियन्त्रण परीक्षण वा प्लेटलेट एफेरेसिस उत्पादनहरूको लागि क्लटिंग परीक्षणहरू छैनन्। यो भिभो प्लेटलेट प्रकार्यमा सही भविष्यवाणी गर्न इन भिट्रो प्लेटलेट प्रकार्य परीक्षणको असक्षमताको कारण हो।
एन्टिकोआगुलेन्ट लिने व्यक्तिहरूको लागि स्थगित अवधि दुई कारकहरूमा आधारित हुन्छ: दातालाई भेनिपंक्चर साइटमा अत्यधिक रक्तस्राव हुन सक्छ भन्ने चिन्ता र दान गरिएको प्लाज्माको क्लटिंग गुणहरूमा एन्टिकोगुलेन्टको सम्भावित प्रभाव। एन्टिकोआगुलेन्टहरू लिने दाताहरूलाई प्लेटलेट एफेरेसिस दानबाट समान रूपमा स्थगित गरिन्छ। यद्यपि, केही रगत केन्द्रहरूले त्यस्ता दाताहरूबाट सम्पूर्ण रगत सङ्कलन गर्न छनौट गर्न सक्छन् यदि उनीहरूले फ्लेबोटोमी साइटमा रक्तस्रावको जोखिमलाई न्यूनतम मान्छन् र यदि तिनीहरूसँग त्यस्तो सङ्कलनबाट प्लाज्मा निकालिएको हो भनेर सुनिश्चित गर्ने विधि छ भने (जसले कोगुलेसन गुणहरू बिग्रन्छ। ट्रान्सफ्युजनको लागि प्रयोग गरिदैन।
विभिन्न विभिन्न anticoagulant औषधिहरूको लागि समय सीमाहरू निम्नानुसार छन्
●Direct oral anticoagulants (DOACs; apixaban, dabigatran, edoxaban, rivaroxaban), fondaparinux, and the low molecular weight (LMW) heparins dalteparin and enoxaparin – Previous two days.
●Warfarin and LMW heparins other than dalteparin and enoxaparin – Previous seven days.
The minimal age for donation is legally established by individual states in the United States and is either 16 or 17 years; donors who are legally minors need written consent of a parent or guardian. Most blood centers do not have an upper age limit for donation; this policy is based on studies documenting that individuals over the age of 65 who met all other donation criteria had no greater frequency of severe or life-threatening reactions and had lower rates of post-transfusion reactions than younger donors
If you’ve ever had to fill out an official document in Nepal—or apply for a visa abroad—you’ve likely hit that sudden speed bump: “Enter your Date of Birth in AD.”
For anyone raised with the Bikram Sambat (BS) calendar, converting your birthdate, legal paperwork, or school certificates into the Gregorian (AD) system isn’t always straightforward. You can’t just subtract 57 years and call it a day!
Whether you need a quick BS to AD converter for your passport application or an AD to BS converter for Lok Sewa forms, this guide breaks down how date conversion works, why the two calendars differ, and how to get accurate results every time.
Why Is Converting Nepali Dates So Tricky?
At first glance, converting between the Nepali calendar (Bikram Sambat) and the English calendar (Gregorian) seems like basic math. In reality, it’s a bit more dynamic:
The Year Offset: Bikram Sambat runs roughly 56 to 57 years ahead of the Gregorian calendar.
Variable Month Lengths:Unlike the Western calendar where months (mostly) alternate between 30 and 31 days, Nepali month lengths change every year.A single month like Baisakh or Shrawan can have anywhere from 29 to 32 days depending on astronomical calculations.
The New Year Shift:The Nepali New Year (Baisakh 1) doesn’t start on January 1st—it lands in mid-April (usually April 13 or 14).
Because of these shifting days, an automated Nepali Date Converter (मिति परिवर्तन) tool relies on precise lookup tables rather than a simple mathematical formula.

Common Uses for a Nepali Date Converter
Having an accurate BS ↔ AD conversion tool saves time and prevents costly errors across several key areas:
Passport & Visa Applications: Overseas institutions and immigration departments (such as for US Study Visas, Australia, or the EDV Lottery) strictly require your date of birth in the Gregorian (AD) format.
Government & Legal Forms:Filling out forms for citizenship (Nagarikta), driving licenses, PAN cards, or Lok Sewa Aayog exams often requires entering dates in both BS and AD.
Academic & Workplace Records: Aligning transcripts from Tribhuvan University or NEB with international university requirements.
Cultural Events & Festivals: Tracking upcoming festival dates like Dashain, Tihar, Lhosar, or Teej on international digital calendars.
Pro Tip: When converting a birthdate for official paperwork, always verify whether your birth month falls before or after Baisakh 1. If you were born between January 1 and mid-April, your AD birth year will be 57 years behind your BS year.If born after mid-April, it will be 56 years behind.
How to Convert Dates: A Practical Example
1. Converting BS to AD (Nepali to English)
To translate a Bikram Sambat date into English:
Identify your exact BS Year, Month, and Day (e.g., 2058 Bhadra 21).
Input the details into a trusted online Nepali date converter.
The converter maps the exact astronomical day count and outputs the corresponding Gregorian date (e.g., September 6, 2001).
2. Converting AD to BS (English to Nepali)
To convert a Gregorian date back to Bikram Sambat:
Select the AD Year, Month, and Day (e.g., August 12, 2026).
The tool computes the day offset from the reference base year.
It displays your Nepali date in both English text and Devanagari Unicode (e.g., २७ श्रावण २०८३ / Shrawan 27, 2083).
Frequently Asked Questions (FAQs)
What is today’s Nepali date (Aaja ko Miti)?
Nepali date converters update daily to show Today’s Date (आजको मिति) in both BS and AD, along with the corresponding day of the week and Tithi.
Why can’t I just use a simple subtraction formula?
Because Bikram Sambat months do not have fixed day lengths every year.One year Ashadh might have 31 days, and the next year it might have 32. A fixed formula will often cause your date to be off by 1 to 2 days.
Is Bikram Sambat used outside of Nepal?
While variants of the Vikram Samvat calendar exist in parts of India, Nepal is the only country that uses Bikram Sambat as its official national calendar system.
